RE: Stack Size
SysGetStackInfo() reports the space allocated for use as a stack. The value
of the stack pointer (SP or a7) tells you where you are in the stack.
I believe SysGetStackInfo() returns the address of the first and last bytes
allocated to the stack, so actual stack size would be (end - start + 1). You
can read the stack pointer with the following:
UInt32 GetSP(void) = 0x200F;
To determine how much of the stack has been consumed; ((UInt32)end - GetSP()
+ 1) bytes.
To determine how much of the stack remains; (GetSP() - (UInt32)start) bytes.

Subject: Stack Size
I got this from another post:
Chris Apers previously wrote:
Is there a way to know the size of the stack ?.
UInt32 GetStackSize( // returns size of stack in bytes
void) // no parameters
{
MemPtr StartPP = NULL;
MemPtr EndPP = NULL;
SysGetStackInfo(StartPP, EndPP);
UInt32 TotalBytes = (Char *) EndPP - (Char *) StartPP;
return TotalBytes;
}
Given StartPP and EndPP you can also determine the amount of stack used and
amount unused.
My question is, how do you use StartPP and EndPP to determine the amount of
stack used and amount unused? SysGetStackInfo always gives me the same
values no matter where in my app I call it.

RE: Fixed string in code.
I'm glad it worked for you :)
BTW, the inline was not because it was small, but to embed the data into
code with the least amount of overhead (2-4 bytes). Other methods generate a
function body and access code (30-38 bytes), which is not necessary.

RE: Fixed string in code.
I routinely place constants in code resources, such as tables and data
blocks that I want literally formatted and quickly referenced. It's also
easy to create any kind of literal resource using the resource compiler.
Normally, however, I don't care about the data being visible while not
executing.
Your issues are that 1) you want the cpp to make a pass on it so the date
and time tokens get resolved, and 2) you want it to be 'in the clear' for
casual observation.
One way - define an inline function like the following, and reference it
somewhere in your code:
#define kIDTag chrisbruner
inline void asm PrvIDTag(void)
{
bra.s @1
dc.b\n,kIDTag,__DATE__,__TIME__,\n
nop
nop
nop
@1:
}
It doesn't have to be executed, but it must be reachable (so it isn't
dead-stripped). In case it is executed, there is a branch over itself. The
NOPs are to help disassembly stay in sync. I'd reference it in a piece of
code that is rarely executed, but will not be optimized out. For example,
your version of RomVersionCompatible().
For M$DOS, the command 'grep -a chrisbruner yourapp.prc' will yield the
line that contains the tag.

Subject: Re: Fixed string in code.
That's exactly the problem. I'm trying to check the compile date and time
from outside the code, so that the palm software can be kept in sync with
other software/data in our system. I need to be able to find the string
using other software and save it into a datafile, which can be verified by
the palm software later when it's running. That way updates can be sure that
they are running with the correct data.
My scheme was to originally have
_PDADATESTAMP
{
char Tag1[12];
char Date[50];
char Time[50];
};
_PDADATESTAMP pdaDateStamp = {chrisbruner,__DATE__,__TIME__};
I find the tag fine, but the date and time are jumbled. Of course when the
palm software starts up it can see them just fine, which leads me to suspect
that the linker is compressing data, and the loader uncompresses when the
palm software starts. Normally a very nice feature, but in this case

RE: Where Can I see the Rom version for treo 650:
This may seem a simple question to most, but there's a catch... You must be careful which method you use to retrieve a ROM or OS version. My Treo 650's disagree internally. For example: My Sprint Treo 650 (CDMA) displays Palm OS Garnet v. 5.4.8 in the launcher, and SysGetOSVersionString() returns v. 5.4.8. However, the ROM version returned by FtrGet(sysFtrCreator,sysFtrNumROMVersion,v) is 0x05403017, which means v.5.4.0r23. My PalmOne Treo 650 (GSM) displays Palm OS Garnet v. 5.4.7 in the launcher, and SysGetOSVersionString() returns v. 5.4.7. However, the ROM version feature is 0x05403017, which again means v.5.4.0r23. However, my Kyocera 7135 (CDMA) and Tungsten T3 agree internally. My Kyocera 7135 (CDMA) displays Palm OS Software v. 4.1 in the launcher, and SysGetOSVersionString() returns v. 4.1, and the ROM version feature is 0x04103000, or v.4.1.0r0. My Tungsten T3 displays Palm OS software v. 5.2.1 in the launcher, and SysGetOSVersionString() returns v. 5.2.1, and the ROM version feature is 0x05213000, or v.5.2.1r0. My code gets the feature and the version string, decodes the version string, compares the two and uses the highest it finds.

RE: DateTimeType converting seconds to string
Katie,
Several problems that could cause a crash:
1. You pass in a (char **), implying you expect an allocated return buffer,
or a reference to some internal static buffer. Instead, you pass back the
address of an 'auto' buffer, one that temporarily exists on the stack only
as long as the CreateWavFileName() function is executing. It is no longer
valid after returning from CreateWavFileName().
2. The declaration char seconds[2] leaves no room for the trailing nul.
You expect two digits but have forgotten about the nul at the end of the
string. It should be at least char seconds[3]. That may also be the case
with your other declarations.
Since you know the specific format, why not format it yourself. Following is
a quick example. I presumed you wanted an allocated buffer returned. If
that's not the case, you can remove that part.
/*
* Returns an allocated buffer at *ReturnFileName, or NULL for failure.
* Caller must free the allocated buffer with MemPtrFree().
*/
void CreateWavFileName (char **ReturnFileName)
{
DateTimeType dt;
*ReturnFileName = MemPtrNew(22);// YY.MM.DD.hh.mm.ss.wav\0
== char[22]
if (*ReturnFileName)
{
TimSecondsToDateTime(TimGetSeconds(),dt);
StrPrintF(*ReturnFileName,%02d.%02d.%02d.%02d.%02d.%02d.wav,

Subject: Reading AppInfo block in DB
Hi All,
I'm having trouble reading the app info block in my DB.
I've written this kind of code before and it works fine when the AppInfo
block is of a known size that can be directly assigned to a C struct.
However, in this particular database, the app info block can be of an
arbitrary size..
I get the app info pointer like so:
appInfoP = (char*)MemLocalIDToLockedPtr(appInfoID, cardNum);
I then assign some local variables with the data contained in the app info
block by cycling through the pointer.
Like:
// number of strings
groupList.SetCount(*appInfoP);
appInfoP++;
// read each string
for(int j = 0; j groupList.GetCount(); j++)
{
do
{
groupList[j]+= *appInfoP;
appInfoP++;
}
while(*appInfoP != '\0');
// skip over null byte
appInfoP++;
After doing this I call:
MemPtrUnlock(appInfoP);
However, my application crahses as soon as the call to unlock the pointer is
made..
If I get the lock pointer and then immediately unlock it without reading any
values, it doesn't crash..
Does anyone know why this is happening and how I can resolve the issue?
Thanks for the help in advance,

RE: Receiving data
On a stream socket, the data never ends. Keep reading until you get all the data you expect (if you know the length), or until the socket is closed. For example, if you connect to a service that sends packets of known length, read the socket until you have received a complete packet, and then repeat as required until closed. Another example, if you are connecting to a server that sends a single stream of data and then closes the socket (a web page, for example), then read the data until the socket is closed by the other end. Even a web page response contains the content length, but you can read until closed just as easily.

Hi,
I need to dial a number on the Treo 600, and it doesn't seem to be working.
It causes a crash, and according to the system log, the application causing
the crash was Phone, and not my own application.
Anyway, here's the code I'm using to initiate the call:
Wait -- one more thing: everything works, if I set confirm to true, or copy

RE: INet.lib confusion
The netErrWouldBlock is normal if you read an empty non-blocking socket. It means your call would have blocked to wait for data. All you do is come back to it another time and try again. If there is data, you will receive it, else you will get another netErrWouldBlock. It is common to keep trying the socket at intervals. You can set the maximum time EvtGetEvent() will wait for a system event. Then, when you receive a nil event from EvtGetEvent(), which will occur at timeout (and other times, as well), you poll the socket for data.

RE: INet.lib confusion
Check out socket notices. You set the socket to send a notice on one or more events, and then go off and do other things until the notice (notification) arrives. OS5 supports only the 'notification' type of notice, on any combination of the following events: netSocketNoticeErr netSocketNoticeUDPReceive netSocketNoticeTCPReceive netSocketNoticeTCPTransmit netSocketNoticeTCPRemoteClosed netSocketNoticeTCPClosed netSocketNoticeConnectInbound netSocketNoticeConnectOutbound Sorry about the outbound connection notice not working. My fault. There are alternatives to non-blocking outbound connection, though.

Re: Background operation on PalmOS
Good suggestion. People have attempted to use real AMX tasks in pre-OS5, which is neither supported nor recommended. I would like to point out right up front that my work does not involve any additional OS 'tasks' of any kind. And yes, it is possible to do background-like stuff with notifications. However, my work is less about background operation and more about application threads that happen to work in the background. I have been called upon to do a lot of communication related stuff, often porting from other operating systems. It is common to have at least a send, receive and service thread, asynchronous I/O and some kind of background presence. Early on (I've been at this since 1996) I got really tired of having to re-engineer everything to the, dare I say, 'frightfully primitive' Palm model, so I created threads, added async I/O, and facilitated background operation. This work has served me well and I'm offering it to the community (in a form yet to be determined).

Works on PalmOS 3.5 and later (including OS5 - haven't tried OS6). 1. Any number of threads, in any number of contexts (app environments). 2. Non-preemptive, with some exceptions. 3. App globals and multi-segment support. 4. Asynchronous socket and serial IO. 5. Timers, events (semaphore, mutex) and queues. 6. Power and sleep management. Caveats: 1. It's PalmOS, so all copies would be shipped with a packet of salt, to be taken a grain at a time. 2. The thread stacks annoy the emulator. 3.

RE: Read about it in the SDK.
First, you increment 'recordindex' before using, so you skip strArray[0] and
potentially write past the allocated array.
Second, since you skipped strArray[0], LstDrawList() tells the list draw
code to dereference a string pointer that is garbage and probably crashes
doing so.

RE: Simple question about how to increase stack size
Stanislav,
You can change the stack size at least two ways;
1) change the requested stack size at build time in the 'pref' resource
2) change the actual stack at run time
The first is simple. For example, if using PilRC, the following is supposed
to work:
SYSAPPLICATIONPREFERENCES ID 0 PRIORITY 30 STACKSIZE 8192 MINHEAPSPACE 4096
Unfortunately, the above statement does not work in our version of PilRC, so
I use the following manual method:
HEX pref ID 0 /*priority*/0x00 0x1E /*minstack*/0x00 0x00 0x20 0x00
/*minheap*/0x00 0x00 0x10 0x00
The second is a hack, but works fine. Note, this method causes the emulator
to complain that the stack pointer is outside the stack boundaries. Turn
that warning off, of don't use the emulator.
How it works: you allocate the stack you'd prefer with MemPtrNew(), save the
current stack pointer, then change the stack pointer to point to the end of
the newly allocated stack, and call your code. When you return, restore the
stack pointer to the saved one, MemPtrFree() the one you created and return
to the original caller. It's easy in assembler. Example:
void asm ExecuteWithNewStack(void (*proc)(), UInt32 stackSize)
{
// allocate new stack
move.l 8(sp),-(sp)// retrieve 'stackSize'
trap #15
dc.w #sysTrapMemPtrNew
move.l a0,(sp)// save new stack base
// call proc using new stack
add.l12(sp),a0 // add 'stackSize' to new stack pointer
move.l 8(sp),a1 // retrieve 'proc'
exg a0,sp // exchange new and old stack
move.l a0,-(sp) // save original stack pointer
jsr (a1) // call proc
move.l (sp)+,sp // restore original stack pointer
// dispose of allocated stack
// previously allocated pointer is still on original stack
trap #15
dc.w #sysTrapMemPtrFree
// cleanup and return
lea 8(sp),sp
rts
}

RE: Question on Socket notifications
The inbound socket activity has already awakened the device and deferred the socket notice. The deferred notification will be broadcast during EvtGetEvent(), which your app is probably blocked in. You need to make sure you defer sleep (see sleep event/notifications and management) long enough to be able to broadcast the notification and return from EvtGetEvent() to do any followup servicing. You can do all of this without fully waking the device (screen remains off), and returning to full sleep when finished. jeff Jeff Loucks Work 425-284-1128 [EMAIL PROTECTED] Home 253-851-8908 [EMAIL PROTECTED] Mobile 253-691-8812 -Original Message- From: Aaron Hansen [mailto:[EMAIL PROTECTED] Sent: Friday, July 01, 2005 9:32 AM To: Palm Developer Forum Subject: Question on Socket notifications Hey folks, I am trying to get socket notifications working and seem to be having problems.

RE: How to get Palm Phone Number
There are several ways, depending on the device and telephony support. Handspring uses the PhnLib. First, use PhnLibGetOwnNumbers() to get the list of phone numbers. Then, depending on phone type CDMA or GSM, extract the number (phnAddrFldPhone) from the first entry in the list. For CDMA, use PhnLibAPGetNth() and PhnLibAPGetField(). For GSM, use PhnLibGetNth() and PhnLibGetField(). Kyocera uses PDQModGetPhoneNumber(). On the old Tungsten-W, you had to read it from the Mobile Panel preferences using PrefGetAppPreferences() to retrieve kFileCMobilePanel/kMobilePanelPrefsId into a MobilePanelPrefsType.

RE: Reciving Data in a Socket
Alexandre,
Use socket notices.
1. Register to receive a notification, either procedural or app launch.
2. Prepare a socket to do what you need to do (stream or datagram).
3. Prime the socket to send a socket notice (notifications are the only type
supported by OS5).
4. When data arrives (or an error or shutdown), a deferred notification will
be sent by NetLib.
5. When you receive the notification, service the socket and then re-prime
the socket (one notice per prime).
A socket can be primed to send a notice on any combination of data receipt,
inbound connect, error or shutdown. Unfortunately, outbound connect was
overlooked.
NOTES:
1. Socket notices use a deferred notification, meaning the notification will
not be broadcast until the foreground app calls EvtGetEvent().
2. Socket notices are one-shot and must be reset after each trigger. You can
do it in the notification handler, if it is convenient.
3. The option argument passed in NetLibSocketOptionSet() in this case is the
address of a void pointer which points to the NetSocketNoticeType. Kind of
confusing.
4. There is sample socket notice code provided in the knowledge base, but it
is not very clear.
Try something like the following to prime the socket to send a notice:
// Refer to NetMgr.h for socket notice options.
Int16 AsyncSocketSetup(SOCKET sock, UInt32 condition)
{
NetSocketNoticeType notice;
void *option;
notice.condition = condition; // some combination of conditions
from NetMgr.h
notice.type = netSocketNoticeNotify;
notice.notice.notify.notifyType = your selected notification ID;
option = notice; // note the address of the pointer is used
if (NetLibSocketOptionSet(
NetLibRefnum,
sock,
netSocketOptLevelSocket,
netSocketOptSockNotice,
option,
sizeof(option),
NetLibTimeout,
NetLibErrno))
{
TRACE(AsyncSocketSetup() cannot set socket notice:
%x,NetLibErrno);
return -1;
}
return 0;
}
Hope this helps.
Jeff

RE: How to prevent the device from going to sleep?
If you invoke modal UI objects, the event loop is out of your hands. Nasty part of doing business with events (especially custom events) or using an event loop. There are several ways to prevent a device from going to sleep. I think all of them have already been mentioned. If EvtResetAutoOffTimer() in the event loop didn't work (modals?), try one of the others, eg EvtSetAutoOffTimer(). To recap: 1. EvtResetAutoOffTimer() simply resets the auto-off timer, but does not deactivate it. If the auto-off timer ever reaches the timeout value (see EvtSetAutoOffTimer()), the device will attempt to auto-off. You must call EvtResetAutoOffTimer() before the auto-off timer counts up to the timeout value. This is useful when you are certain you can keep up with the auto-off timer (beware of modals and long compute bound procedures). 2. Use EvtSetAutoOffTimer() to modify the auto-off timer. I believe setting the timeout value to zero disables auto-off. Be careful that you don't leave it disabled, so that it never goes to sleep, unless draining the battery is really what you want to do :) 3. Register for and intercept the sleep notifications. There's a white paper and a discussion under notifications in the companion. 4. If you are in charge of the event loop (beware of modals), you can waylay the power-off and auto-off keys.

RE: Network

I see a lot questions like what event is generated when such-and-such happens? Here are some suggestions: 1. Hook your device up to a debugger and watch what happens when you do such-and-such. 2. Or, use the emulator and log events while you do such-and-such. 3. Or, write an app to simply dump the contents of each event returned by EvtGetEvent(). Pick your favorite. I usually use the third option, and write to the serial port which I connect to a terminal emulator. You can do this realtime while an app is running. If you don't want to use the serial port, write to a memo or directly to the screen in a scrolling window. Be creative.

A7 points to the current top of a stack (always valid). The stack is allocated in the dynamic heap. A6 is the 'frame' pointer (sometimes valid). The frame exists on the stack.

RE: NVFS articles online
Doug, You are correct, it answers one interpretation of the question. The question was What did NVFS buy us? Seems like its just breaking a lot of stuff IMHO, the question was not what was intended, but what did we get. We got a non-determinant and unreliable implementation. I'm all for reliable non-volatile storage, but I'll trust NVFS as a non-volatile alternative, and admit it has bought us something, when it is able to survive an unexpected reset, which at this point is all too frequent. BTW, backup software is not the only way to use SD cards, or other form of non-volatile storage. Apps have always been able to read and write them directly. NVFS tries to do this automatically, but IMHO, gives us a false sense of security by having us believe that our stuff is magically backed up. NVFS does not (yet) do a deterministic job of automatically backing stuff up. This is very important, if data state is important.

RE: Global variables and special launch codes
Globals (globals, statics, and multi-segment jump tables) are stored in a chunk of dynamic heap that is only allocated for the app when it is launched normally. This memory is available to the app via M68K register A5. The compiler knows this and generates code that accesses globals relative to A5. If you attempt to execute your code without A5 pointing to you globals, bad things happen. Code that expects to be executed without a valid A5 should not use globals of any kind. There are alternatives. A common solution is to: 1) MemPtrNew() or MemHandleNew() a structure that contains all the info your code needs. Be sure to MemPtrSetOwner() to 0, so the memory is not automatically freed when your app exits, unless that's okay. 2) Optionally use a feature to remember the pointer or handle that you allocated in step #1. 3) Pass the pointer or handle as a user data pointer or reference in any API that sets up your code to be called back. Those situations that do not provide a user data pointer or reference can rely on the feature.

RE: T5 storage issues
Sorry, for the length of this response. I had to leave for my son's birthday. I would have liked to have been in the thick of this. After all, I started it :) I have a theory that it's a little more complex than that. I think what happened is that the T5 was supposed to be an OS 6 device, but PalmOne punted at or near the last minute and decided to make it an OS 5 device. Whether this was due to PalmOne's unwillingness to Thanks Logan, but from the developer and user's perspective, it doesn't matter what predicament they (PalmX) faced, or that they didn't intend to break anything. What's important is that they knowingly DID depart from some very important things and broke several other things. (with battery backed) You reset and you've lost nothing. The new way buffers all our nice important data in volatile storage. We can't flush it and we can't know when the OS has deigned to write it through to flash, so we never really know when the data is safe. Scratch reliability. Wrong! While we can't flush the cache and *empty* it, we can force the cache to be committed back to NAND and therefore be safe from loss. But then with your attitude of Forget the white paper, I guess you'll never read about adding calls to DmSyncDatabase() to force this commit to occur. Thanks Doug, but many of you still consider manipulating a single record and then syncing it, the only kind of database activity used. Our app requires a fairly complex data caching scheme. It requires simultaneous use and update of tens of megabytes of data. The NAND flash and device performance in general cannot tolerate constantly syncing each database every time a cache link or update is performed. We'd quickly wear out the flash, our patience or both. My attitude is not the question - I've read the white paper. It doesn't address complicated apps. It gives simplistic bandaids for general purpose use. It does not address our issues. I don't have any problems with realiability in my tests, even with unannounced resets. But then, I read the white paper... Please lay off the white paper. Some apps can accept simple workarounds. Your issues may have been resolved, but ours remain. We use NetLib over the cell phone on the Treo650. That's bad enough on any device. It's even worse on Palm devices. Resets are simply a fact of life. Until NVFS, we could endure them. Now, however... I'm planning on doing a talk on NVFS at PalmSource 2005; I'm still gathering all my information and seeing just what I can get cleared by legal, but I hope to have a lot of information about the initial implementation, the changes made for the Sprint Treo 650 update, and, if I can, future directions for this technology. I appreciate you in the forum Ben, and I'll look forward to your presentation, but I'm afraid I'm less interested in the history and good intentions of NVFS, than I am hearing how it will be fixed. For those of us who can't make the conference, I would presentation materials or a white paper or something will be released following the conference. Ditto. IMHO I don't think data loss is a real threat for most users and I don't think flash memory is better and more reliable than it's counterpart. I agree Miguel. Even if the NVFS implementation worked reliably, it only solves lesser problems. It cannot be argued that it provides better, or even the same data reliability during use, only that it doesn't forget what you can manage to stuff into it before the platform croaks out from under you. I for one feel that non-volatile memory is one of the most important additions to the handheld world in a long time. That said, I can't speak to how well it's been implemented on the T5 and Treo 650, because I haven't used either device yet. The battery on my Simulator works great though... :) I have no problem with non volatile storage Mark, only as you say, the implementation. If they couldn't get it right, they could have made it a built in SD card, and left the storage heap in battery backed ram. At least then it would be up to us how we choose to impose reliability. I think you may be underestimating the significance of non-volatile memory. And keep in mind that one real advantage is the T5 does not require *any* battery power while off. So it can sit in a drawer or purse for whatever length of time, and when you pull it out it is still ready to go. This may encourage people who don't use it as often, to start using it more and/or perceive it as more reliable. Please see my offhanded interim solution in the previous paragragh, Doug. You don't have to throw out the value of non volatile. The same can be accomplished in any previous device that supported an SD card. They didn't have to complicate our lives with a poorly implemented and MANDATORY NVFS. I'm not saying non-volatile memory is less or not reliable but what I think is that many times the phrase you won't lose your data is misused to improve the perceived reliability, and perceived !=
RE: T5 storage issues
Excuse me ahead of time - flames ahead... It wasn't supposed to break anything; the implementation that shipped on the T5 is a bit buggy, but palmOne and PalmSource are working on improving it and making it work much better with new software. Okay, I've been holding my tongue for a long time... Anyone could take one look at the PalmOS plan to improve things with this lame NVFS stuff and know there was going to be trouble. Right off the bat their marketing hype claimed improved reliability, performance and capacity. First of all, the old way provided immediate write to battery backed storage. You reset and you've lost nothing. The new way buffers all our nice important data in volatile storage. We can't flush it and we can't know when the OS has deigned to write it through to flash, so we never really know when the data is safe. Scratch reliability. Second, the performance sucks rocks for many of us who use the storage heap a lot. No problem for the simple little app that gets a record, the user plays with it for a while, then writes it back out. For those of us with lots of dynamic data, it's an unreliable pig. Third, I'll give PalmWhomever half credit - they sorta solved the ugly 512 byte sector fiasco. So just how many DECADES have the rest of us had blocking and deblocking figured out? How many file system failures did it take for the rest of the known world to settle on a few working paradigms? And somehow Palm couldn't maybe just look around a little and figure it out, too? So, all in all I wish PalmWhomever would stop yapping about all the advantages of this NVFS stuff, and just admit that it's a cheap way to build high capacity devices. We'll just have to suck it up and deal with the wild departure from the old way, the poor, indeterminant lack of reliabilty, and the lack of performance. We can handle that. On the PluggedIn site, please look for a whitepaper called NVFS White Paper in the Developer Resources section. It was last updated in March Forget the white paper. How about a big my fault paper, and then some plan for fixing it.

RE: fatal exception from multiplication in gcc compiled callback
The 68EZ328 indeed supports a mulu instruction, but you'll notice it is a
16x16 operation. In other words, a mulu.S. You were trying to use a mulu.L,
which is not supported by the EC000 core.
Your original callback uses a global value to locate the multiply code
[move.l [EMAIL PROTECTED](%a5),%a0]. It is found relative to the A5 register,
which is reserved as the globals context register. If the A5 register is not
correct when CallbackPeckAudio() is called, you will not be able to
correctly locate the desired global value. In other words, the calling code
may have it's own globals context, which could mean that the value of A5 has
been changed to meet the calling code's needs, and is wrong for your needs.
If this is the case, you should either 1) not refer to globals in your
callback, or 2) pass your A5 value to the callback and use SysSetA5() to
temporarily set A5 for your use.
This is all best accomplished by creating a structure containing everything
needed by the callback, and then passing the address of the structure to the
callback as a userdata pointer. The structure could contain your own A5
value, giving you full access to your normal globals, or it could contain
everything needed without globals, or some combination.
You already do the structure bit with struct PeckAudioType. You could
either add your A5 value to the structure, or add a reference to the global
in the structure. Whatever works best for you.
If you'd like info on a (32x32).L, that's another email.
Sorry so long winded.

Subject: fatal exception from multiplication in gcc compiled callback
I'd like to implement a UInt32 x UInt32 multiply (discarding the most
significant 32 bits of result) in a callback for a sound stream, but the
multiplication is causing a fatal exception (on a Zire 31). From
looking at the assembly language produced by gcc, the reason for the
exception appears to be the attempted use of a global (not available in
callback).
Here's the applicable data structure and code:
typedef struct PeckAudioType {
SndStreamRef streamRef;
UInt32 fileSize;
UInt32 fileOffset;
FileRef fileRef;
UInt32 bufferCount;
UInt32 s;
UInt32 a;
UInt32 b;
} PeckAudioType;
Err CallbackPeckAudio(void *pUserData,
SndStreamRef stream,
void *bufferP,
UInt32 frameCount)
{
PeckAudioType *pPeckAudio = (PeckAudioType *)pUserData;
Err err;
/* Read next sound stream buffer from file. */
err = VFSFileRead(pPeckAudio-fileRef, frameCount*2, bufferP, NULL);
pPeckAudio-a *= pPeckAudio-b; /* LINE 8 */
- - -
The assembly language for Line 8 is:
.globl CallbackPeckAudio
CallbackPeckAudio:
...
.ln 8
move.l [EMAIL PROTECTED](%a5),%a0
add.l #__mulsi3,%a0 /*JANE2*/
move.l 28(%a2),-(%sp)
move.l 24(%a2),-(%sp)
jsr (%a0)
addq.l #8,%sp
move.l %d0,24(%a2)
- - -
Noting that changing the multiplication to addition causes an in-line
calculation and allows the sound stream callback to work properly, I
tried gcc's inline assembly.
Err CallbackPeckAudio(void *pUserData,
SndStreamRef stream,
void *bufferP,
UInt32 frameCount)
{
PeckAudioType *pPeckAudio = (PeckAudioType *)pUserData;
Err err;
/* Read next sound stream buffer from file. */
err = VFSFileRead(pPeckAudio-fileRef, frameCount*2, bufferP, NULL);
// pPeckAudio-a *= pPeckAudio-b;
__asm__(
move.l 28(%a2),%d0;
mulu.l 24(%a2),%d0;
move.l %d0,24(%a2);
);
- - -
However, that results in the compiler error: invalid instruction for
this architecture; needs 68020 or 68030 or 68040 or 68060 or cpu32 or
5200 or 5206e or 5307 or 5407 -- statement `mulu.l 24(%a2),%d0'
ignored. That's a bit confusing because the MC68EZ328 User Manual
lists a mulu instruction in its EC000 instruction set. I've never had
to mess much with the prc-tools. Do I need to somewhere specify that I
want gcc to produce MC68EZ328 instructions?
Before I get into this any deeper, I'd like to ask how others have
implemented multiplications from within callbacks.
Thanks,
Greg

RE: change os of palm
Yes and no. How's that for an answer! First, let me tell you that it is entirely possible to do what I think it is you want to do. My Palm experience includes principal hardware engineer for the PalmIII, and engineering team member for the PalmVII, Tungsten-W, Tungsten-T, and I've written several alternative OS's for palm devices. It can work just fine. You need to know a lot about the device, though. Direct and complete hardware access is only slightly more difficult on any of the ARM platforms, but both ARM and 68K platforms are essentially open to the world, or can be made so. For example, you have full access at all times on any of the 68K devices. The only area that may cause you trouble will be the things your OS must do to either make the hardware function as designed, or keep the hardware from interfering with whatever you may desire it to do. The Palm devices are not designed as generic microprocessor platforms, but are highly integrated systems. Certainly, you can disable system features to the point that you have simply a processor and memory, but to be useful, you would need to re-enable features such as serial and USB ports, IrDA, battery management, LCD, backlight, touch screen, buttons, wireless subsystems, audio subsystems, and the like. You would be limited to doing this in accordance with the way the device was designed, or it may not function. To make a long story short, you would need a system description and schematics to the extent that you could determine how, where and why the components are connected, and you would need to understand how the PDA was designed to function as an integrated system. After that, it's a piece of cake :) Jeff PS. Someone suggested writing your OS on top of PalmOS, or you can write it on top of the existing HAL/DAL. This is often done if it is a proof of concept, something like a school project, or a value-added/embedded use for the device.

RE: Exporting reports
No, not 'difficult', but maybe not that interesting :0 Oh, sorry, that was rude... What I mean is that PDA apps generally don't do things that, by their nature, aren't readily accomplished on PDAs. No, that cuts the PDA a bit too much slack. Instead, developers have adapted to the limitations of PDAs, and try to reason a different approach. Some thoughts: 1. Stream your report to a text file on an SD card. 2. Paginate your report, each page to a memo or a record in your own database. 3. Leave the data in it's raw, and I assume smaller state, and reproduce the report format on the fly. 4. Compress the report - zlib does ok with fluffy text. 5. Stream to a common DOC format and view with the appropriate reader. 6. Similar to 3 and 4 above, I've written self extracting/viewing report apps by appending compressed data resources to a common execution resource. I've done all of the above. It depends on which suits best, given the needs and limitations.

RE: Exporting reports
Uhm, I thought that generating a report on the PDA and sending it to a PC or to another PDA is something that PDAs are normally used for? Quite right, but not necessarily in destination format. PDAs are commonly used to acquire data of many forms, and sometimes this data is viewable, to some extent, on the PDA. But, if it is ultimately destined for a PC or other resource 'unlimited' platform, it is often left as an exercise for the reader to format and display the data. 1. Stream your report to a text file on an SD card. Not good; the receiving device might not have an SD card. Memory card readers are cheap. Cheaper, at times, than the effort to do without. Most PDAs have them and most recent PCs have them. You might be faced with a PDA that doesn't specifically use the SD format. That would be a problem, although a local PC with a multiformat reader could convert, in a pinch. I was thinking of splitting the report into multiple memos as a possible (albeit ugly) solution. Is this what you mean by the above? Yes. It's ugly, but expedient. I often do tracing to memos, as some devices don't have serial ports %^$#%$#. What is considered a common DOC format in PalmOS and what is the reader for it? I thought it was the memo and MemoPad respectively. MemoPad is simply available, but certainly not optimal. Kind of like the PalmVII using the Mobitex pager network and proxy for network access. As for a common DOC format, there are several. You'll have to ask around. Am I stuck with writing a conduit that translates the report into a TXT file? Maybe, if it works for you. Can MemoPad *view* memos larger than 4 Kb? Can I somehow disable the ability to edit a memo (e.g., write-protect it or something)? AFAIK, MemoPad is limited to 4Kb for convenience. The size limit allows easy access to existing UI resources. There are open source office automation tools out there. Maybe one of those could be used to generate and read the report on the PDA, and then 'standard' office tools could be used on the PC. Doesn't address getting it to the PC, though. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
RE: change os of palm
Yes, the hardware will do whatever you tell it, assuming it can. Beware the 'halt-and-catch-fire' opcode :) But, that doesn't mean the device will end up acting like a PDA. There is almost nothing the device does for itself (in hardware), so the hardware must be closely managed or you don't get a functioning device. Imagine a PC without a BIOS. Some devices utilize custom hardware that depends on special attention by the driver software. You might be able to replace the OS, leaving the HAL and DAL (hardware and device abstraction layers) in place. No matter the approach, you'll need to be intimate with the device architecture. If, on the other hand, you don't need it to be a PDA, but instead want it to run a robot or control a blender, then have at it and YMMV!

RE: Notifications buggy on NVFS as well?
Yes, that's probably some of what we've seen, too. Our company has put T5/650 dev on hold. The NVFS has thrown us too big a curve. We have a DM intensive app, with many small and large records, lots of notifications and intensive NetLib activity. It was hard enough on the much more reliable devices.

RE: EvtGetEvent on T3
EvtGetEvent() will return no later than your timeout (give or take). On
the real device, something is demanding attention at flank speed.
EvtGetEvent() has no way to tell you it isn't returning an event. It always
returns an event, just sometimes it's a nilEvent. Better yet, the nilEvent
may mean something to someone somewhere for timing or whatever, so you
generally have to treat them all as real events.
The TC does the same thing.

Subject: EvtGetEvent on T3
The EvtGetEvent function behaves different on T3 simulator and real T3
The timeout parameter in the EvtGetEvent specifies the number of timer ticks
before checking if there is an event in the event queue. With the value set
at -1 (evtWaitForever) the T3 only wakes up if there is an event. For any
other value, it wakes up every timeout timerticks to check for an event.
If there is nothing, it sends an nilEvent into the event queue.
The code below works fine on the T3 simulator (OS 5.2.1) where the dot is
stepping across the screen at a 1 step per second (100 timerticks per
second). When you move the stylus over the screen sysPenMove events are
generated which make the dot speed up when ever the stylus is moving.
But;
On the real T3 (the same version:OS 5.2.1) however, the speed at wich the
dot moves is irrelevent of the parameter of 100 in the EvtGetEvent function.
It always moves at 100 dots per second. Note that the number of timer ticks
per seconds is 100.
Anyone know why the real T3 is not behaving??

RE: EvtGetEvent on T3
Oh yes, forgot to suggest something. If you wish to do timing with EvtGetEvent(), keep track of the next system tick that you care about and pass the difference between now and the desired system tick as the timeout to EvtGetEvent(). On return, check to see if you've reached your desired tick. Take care as 'timeout' is an Int32, so watch for overflow/underflow and 0/-1, as they mean something special.

RE: EvtGetEvent on T3
I suspect one or more comm stack (or other driver) is needing to poll. EvtWakeup() can be called by anything and will wake up the foreground. If there are no real events, EvtGetEvent() will return a nilEvent. EvtSetNullEventTick() can be called by anything to set the minimum ticks until an EvtWakeup() occurs. Libraries, extensions and drivers will use these calls to wake the foreground as necessary to keep the OS alive. Remember, almost everything happens in either EvtGetEvent() or in the event handlers immediately following.

RE: Treo 650 SysGetROMToken()
The normal (old?) Palm way to retrieve the device serial number (assuming it
has one) follows. If the first byte == 0xFF, there isn't a serial number:
{
UInt8 *p;
UInt16 size;
err = SysGetROMToken(0,sysROMTokenSnum,p,size);
}
Handspring does it a different way. I suppose if the call returns an error,
there isn't a serial number:
{
char buf[32];
UInt16 size = sizeof(buf);
err = HsGetVersionString(hsVerStrSerialNo, buf, size);

RE: USB has replaced serial
The Palm SDIO Bluetooth card is implemented in two parts; an SDIO-serial controller internally wired to the Bluetooth chipset with tx/rx/rts/cts. If you want to part with your Bluetooth card, you could open it up and patch into the serial port. If you're careful, you wouldn't necessarily break the Bluetooth functionality, but it's pretty tight on the pc card. There may be other SDIO cards implemented this way.

RE: Are notifications pointing to functions bad?
You need to make sure your registered functions don't move around on you, because the OS will not automatically adjust them. You do this by opening the application database (and overlays, as necessary) and locking the resources. The OS does this for you when you run your app, but unlocks and closes the app when you exit. You need to do it in addition to the OS, so that when the OS unlocks and closes, you still have them open and locked.

this function. It claims to be able to get a list of numbers on both GSM
and CDMA phones, but there is very little documentaion for it.
It is declared in HsPhoneNetwork.h as :-
Err PhnLibGetOwnNumbers (UInt16 refNum, PhnAddressList* ownNumbers)
and a PhnAddressList is typedefed in HsPhoneTypes as :-
typedef VoidHandPhnAddressList;/** Description */
Has anyone else used this function? I sthere a better way of getting the
phone number?

RE: DmDetachResource problems
You are confusing resource index with resource ID. Look closely at the
following definitions and you will see that DmDetachResource() requires the
index (UInt16) of the resource to detach from the database, while the
DmAttachResource() requires the resource ID (DmResID) of the resource to
attach to the database.
You must DmFindResource() to get an index, or otherwise know the index,
before you can detach or remove the resource.
Err DmAttachResource(DmOpenRef dbP, MemHandle newH, DmResType resType,
DmResID resID);
Err DmDetachResource(DmOpenRef dbP, UInt16 index, MemHandle *oldHP);

RE: Where are the emulator ROM images????
I came into this thread late, so please excuse me if I cover ground already covered. There is a piece of code floating around the net, maybe even around here somewhere :), that will extract a ROM image from an actual device. Older ROMs can be extracted from older devices. Older devices are available really cheap off eBay or, (ahem) borrowed from others.

The game that I wrote (see my earlier thread about AccessorDispatch) is a fairly simple one that I intend to release as freeware, mainly because it will be my first public offering of a Palm application. (Still needs a bit of work, though.) So, it would fit into the non-paying Palm market that Jan mentioned. Also, as I mentioned before, my own Palm PDA is the m500 running OS 4.0, and is quite sufficient for my needs. I like the slimmer case that can fit in my shirt pocket (WITH my reading glasses case, no less!) and, as I also mentioned, I much prefer the original Graffiti over Graffiti 2. (My other half has a Tungsten E. I find it is slower to write in Graffiti 2 than in the original Graffiti, because of those extra strokes.) MOST of my friends with PalmOS-based PDAs have older OS versions (OS 4.0 or earlier; not just Palm, but also Sony Clie, Handspring Visor, etc.) (Abeit, I *do* consider my Tungsten-E-touting wife to be my friend, too. ;-) As well, my next major Palm project will involve an application for a particular hobby market. I expect that most users for this application will still be ones with older OS's. So, from my own experience, I have to disagree with the thinking that writers of new applications should not make any attempt to support older OS's. If an application does not necessarily need colour or any of the newer features of the more recent Palm's, (navigation rocker, etc.) then there should be no reason to leave users of older Palm PDA's behind. Sure, maybe the bigger software market consists of corporate types whose companies can buy the latest and greatest Palm PDA's for them, but there is still a considerable base consisting of home users who cannot afford to upgrade their PDAs every three months. Well, that's my CDN$0.02 anyway. (That's gotta be at least worth half a cent US. :) Oh, that's another thing. The average Canuck has to work about 1.5 times longer than the average USian to pay for those expensive Palm devices! So, we have have more incentive to make the older ones last a bit longer. And sorry about my earlier rant. It came from the frustration of learning that I cannot obtain the earlier OS ROM images (which is still a frustration for me, but I should not have ranted, even though I still think Xerox are The Bad Guys in all of this).

RE: Debug app works, Release doesn't
CtlGetLabel() is defined as returning (const char *). The compiler will complain that you are assigning a (const char *) to a (char *). The 'const' keyword is the issue. The 'const' tells the compiler to treat the value as non-writeable, in this case the data the returned pointer points to. AFAIK, you can (cast) away any declaration. const char *p = char * // okay - the compiler can accept writeable as non-writeable char *p = const char * // not okay - the compiler cannot accept non-writeable as writeable char *p = (char*) const char * // okay - you are overriding the compiler with the cast Jeff Loucks Work 425-284-1128 [EMAIL PROTECTED] Home 253-851-8908 [EMAIL PROTECTED] Mobile 253-691-8812 -Original Message- From: Robert Moynihan [mailto:[EMAIL PROTECTED] Sent: Thursday, January 06, 2005 7:14 PM To: Palm Developer Forum Subject: Re: Debug app works, Release doesn't Chris Tutty wrote: From: Robert Moynihan [EMAIL PROTECTED] (char*) s = CtlGetLabel(GetObjectPtr(ReadyButton)); ... that might get rid of your error message, but might not solve the problem that you are asking about. How on earth is this going to make any difference? Aside from the questionable approach of trying to eliminate a warning rather than fix the underlying problem, how would casting a variable defined as char * to char * change anything. Actually, I did make a mistake. I meant to write (Char*) instead of (char*). The docs say the prototype is... const Char *CtlGetLabel(const ControlType *controlP) ... so I gave a try casting it exactly as the prototype and it eliminated the error message. I didn't know WHY it worked, so, not understanding all the mysteries of compilers, I then went on to see if I could figure out what was happening. I originally thought that Char* and char* were the same, and the ONLY thing that I changed between the 6 trials was the case of the 'c' in the declaration and cast: All 4 of these give the warning message: char*s; s=CtlGetLabel(GetObjectPointer(DBTypeTriggerID)); Char*s; s=CtlGetLabel(GetObjectPointer(DBTypeTriggerID)); char*s; (char*) s=CtlGetLabel(GetObjectPointer(DBTypeTriggerID)); Char*s; (Char*) s=CtlGetLabel(GetObjectPointer(DBTypeTriggerID)); These 2 don't: char*s; (Char*) s=CtlGetLabel(GetObjectPointer(DBTypeTriggerID)); Char*s; (char*) s=CtlGetLabel(GetObjectPointer(DBTypeTriggerID)); This all feels very odd to me.

RE: Difference between NULL and 0?
I apologize ahead of time for my verbosity. Those who know me rarely involve me in a conversation without having a pre-arranged escape plan. Okay, the curmudgeon's gotta speak. Generally used to make a null pointer clear, NULL has been simply eye candy for the value 0. But recently, I've been finding places where a comparison against NULL gives different result than against 0... ...This sucks because I haven't figured out where it should be NULL and where it should be 0 I agree. Precisely my point. NULL has been used incorrectly long enough that it is differentiating 'C' dialects and breaking code. Since some mistakenly define NULL as '(void*)0', you should only use NULL with pointers, and never to mean zero in a mathematical sense. Are you using NULL only with pointers and you still have problems? Are you only using the assignment operators and the equality comparison? One thing to try. Definitions of NULL are conditional on NULL being undefined. If you superceed the definition of NULL with '#define NULL 0', does your code work? (Note: the following is agreement and commiseration, not argument :) Some references: KR, 1st ed, pg 97 #define NULL 0 KR, 1st ed, pg 192 (due to nonportable pointer differences)...it is guaranteed that assignment of the constant 0 to a pointer will produce a null pointer distinguishable from a pointer to an object. KR, 2nd ed (ANSI), pg 102 Pointers and integers are not interchangeable. Zero is the sole exception: the constant zero may be assigned to a pointer, and a pointer may be compared with the constant zero. The symbolic constant NULL is often used in place of zero, as a mnemonic to indicate more clearly that this is a special value for a pointer. NULL is defined in stdio.h.

RE: Difference between NULL and 0?
Okay, the curmudgeon's gotta speak. Generally used to make a null pointer clear, NULL has been simply eye candy for the value 0. NULL is often confused with NUL, which is simply eye candy for the character value of 0. In addition, NULL has been used as a scalar in logical or symbolic math expressions, again simply to mean 0. That's the problem with semantic candy. You use it for a while and you begin to believe it is something special, when all along it's been just a mneumonic. '0' is, indeed, a special value in C, and always has been. NULL has from the beginning simply been a convenientce, and is defined as just 0; not (void*)0, and not const void *NULL = 0. If defined as anything but 0, it's just wrong, and code may break. Practically speaking, using NULL only as a pointer value of 0 should work no matter how it's defined. Other uses will probably break, since you may encounter a definition other than 0.

RE: Difference between NULL and 0?
No bug, just plain C. I guess we should both be ashamed, because I do the same type of thing. Not because performance is any better, as compilers pretty much do what they want these days, but because it simply speaks to me. It can be faster to write and easier to read, but only to those who think in the language. I began my career enamored with the possiblilty of writing entire routines on a single line. I still prefer it, because I despise having to search pages of comments and white space to find that one fragment of code. Others, however, will have trouble with it. It doesn't 'speak' to them. I've known some who would snicker and move on, but others who would demand I be burned at the stake! For their peace of mind I try to avoid the abuse of coding tricks.

RE: Socket Notification
What kind of 'crash' happens? The mechanism is stable, and I use it a lot. Several thoughts; 1. Which Treo and what version of OS? I assume Treo 6x0 and OS5, since socket notices were not announced until OS5. 2. I assume you are using the system notification mechanism of socket notices, since I believe that's the only one supported on OS5. I ask, because I do not know if the other socket notice methods are not allowed, or are simply not supported (in other words, weren't ported or don't work). 3. Prior to OS5, the system notification was broadcast deferred, which means you would receive it in the context of whomever performed the next EvtGetEvent(). I do not know how it is implemented in OS5, so I would suggest you not rely on the application context being correct/predictable at the time the system notification is delivered to your handler. For this reason I have always passed a reference to the application context, usually just a copy of the A5 register. I set the A5 register to that of my application, do what I have to do, and then restore the A5 register. This assumes you need access to your application globals. If you do not, choose your own mechanism. Sorry to be so vague. Do you have more detail?

Has anyone seen this before.I m not sure of the stability of this mechanism since its not well documented and not widely used by many people. Can anyone help on this. thanks regards rachna -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
RE: Debug on Treo 600
Be careful with the aftermarket power supplies. This applies to cables we've found in several 'reputable' stores, not just the internet. While the cables worked just fine, the wall warts produced neither sufficient voltage nor current to power or charge the device. I ended up splicing in some known good 5V1A wall warts. However, if you're not concerned with powering the device, we've not had any trouble with the cables themselves.

Am I going the right way here: http://web.palmone.com/products/Product.jhtml?id=330002cat=310004 That looks like a Treo 600 serial cable so that should do the trick. It's $30 It looks like you can get the same (or similar anyway) cable from a number of folks on eBay for under $10 (plus shipping). I searched for Treo 600 serial cable on eBay and found several listed at about $9.95. Since the Treo 600 uses the same connector as the earlier Treo 180/270/300 devices, a serial cable for one of those phones also works for debugging. I think a lot of the eBay cables are actually just older gear. The phone accessory market is also a very high profit market; resellers are often able to get a $30 accessory for under $5, so there is lots of room for price adjustment in the unauthorized sellers market. -- Ben Combee, Technical Lead, Developer Services, PalmSource, Inc.

RE: console port for debug?
Connect a terminal emulator to the Palm serial port, open the console port and write to it. What you write will be displayed on the terminal emulator. Some issues: 1. Use a serial HotSync cable. 2. Make sure the terminal emulator serial port is configured the same as the Palm serial port (baud, parity, stop bits and flow control). 115200 baud (8N1) works well for me, with hardware flow control enabled. 3. If you are trying to debug a fatal situation, insert a SysTaskDelay() (of appropriate length) after each write to allow the serial buffers to empty before the Palm device crashes. I use a trivial PC program that simply copies bytes from a serial port to a window. Works great.

RE: question about record indexing technique
If you must rely on the sort index, leave 'deleted' records in place and simply mark them deleted. You can reuse the records by linking them together in a 'deleted' list.
