Re: Bitmap offscreen window larger than 64KB?
Is it possible to use BmpCreate() to create a bitmap larger than 64KB, say 640x480 8bpp, and use it to build an offscreen window for double-buffer paint purpose? Or I have to draw such large dynamic BMP with WinDrawPixel() directly on the screen? BmpCreate can allocate memory chunks 64K however, you cannot save them complete in a single resource. you are free to allocate a bitmap of 640x480 @ 8bpp if there is sufficient heap space and then you must fill the contents of the bitmap yourself. 640x480 = a lot of memory. you may want to also use a different technique. --- Aaron Ardiri[EMAIL PROTECTED] CEO - CTO +46 70 656 1143 Mobile Wizardry http://www.mobilewizardry.com/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

PalmGear StreamLync MathLib, etc.
Since I haven't a response from PG on this yet (after a week), and there are likely others in the same boat on this list, I figured I'd ask this here as well. I have an app that is now partially dependant on MathLib. I say pertially dependant, because only one feature needs it, and the app will run without that feature if the library isn't installed. I'm planning to bundle the current version of MathLib with the app, but I'm at a loss as to what to do with PalmGear's StreamLync auto-install with this. The library may already be on the device, or may even be in the ROM (the case with Handspring Visors, at least), and wouldn't need to be reinstalled. The question, then, is should I set it up to be auto-installed?

RE: Recomnd 16-Bit editor/converter?
For anyone following this thread - it's nice to note that while the 24bpp version starts out (as 1/4 of the 320x320 screen) at 76K, pilrc converts it nicely to a 16bpp image and the result generated by adding a 4k 1bppD1 version, which is required to satisfy some limitation or other (is this still the case, Ben?), like so: BITMAPFAMILYEX ID ULHome BEGIN BITMAP ULHome1bppD1.bmp BPP 1 DENSITY 1 BITMAP ULHome24bppD2.bmp BPP 16 DENSITY 2 END makes a bitmap family resource that is about 55K and looks just gorgeous. My mistake was that when I added the 24(16) bpp image version, I didn't delete the 8bpp image that I had been using, which made the result well outside the legal limits. However, CW9.0, rather than politely mentioning the fact that the file or resource was too large, just crashed and disappeared, which made it rather frustrating to discover the root cause. Ben now assures us that the 9.2 version has added some manners to the linker and now gives the appropriate error.

I have read somewhere that palm devices dont have any MMU.

Does that the reason why any resource in Palm cannt be larger than 64K ? And thencannt I hide the physical addresses behind the handles ? I thought a handle is really a pointer to pointer. I particularly wanna know more on how does the system make up for lack of a typical MMU ? The Dragonball processor doesn't have a MMU, but the existence or lack of a MMU is not really related to how the PalmOS memory manager works. Grossly simplified, an MMU is used to map a memory address to some other address. This is useful in a multitasking OS so that each process thinks that its memory starts at address 0. The MMU takes care of mapping the process' virtual address to a real physical address. At a higher level, you still need something to manage the memory space so that when an app calls malloc, or MemHandleNew, or whatever (including indirect calls through the new operator), the app gets something, and when the app frees up the memory (via free, MemHandleFree, delete, etc.), the space is again marked as free. This is also a called a memory manager, but has nothing to do with the MMU. A memory chunk is just an arbitrary name that the PalmOS developers gave to a piece of memory that is managed by the PalmOS memory manager. Every OS call that allocates memory (MemPtrNew, MemHandleNew, MemHandleResize, DmNewRecord, DmResizeRecord, etc.) will eventually get a chunk that the memory manager has decided it can have. The 64K limitation I think is an arbitrary choice. If I recall correctly, the chunk header allows up to 16M chunks, but they limit it to 64K because the hotsync protocol only supports up to 64K record sizes. -- Dave Carrigan Seattle, WA, USA [EMAIL PROTECTED] | http://www.rudedog.org/ | ICQ:161669680 UNIX-Apache-Perl-Linux-Firewalls-LDAP-C-C++-DNS-PalmOS-PostgreSQL-MySQL Dave is currently listening to Elvis Costello - No Dancing (My Aim Is True) -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

nice (though I realize that is unlikely for Palm OS).
2? Fine. 4? Fine. Just not 3! ;-) (just kidding)
Isn't the advantage of tabs that if you and I are sharing code and using
well-mannered IDEs, you can set your tabs to be 2 spaces wide and I can set
mine to 4 spaces wide, and we're both happy?
I expected more guff over the { and the } than the tabs and spaces!
On a slightly related note, I've always thought that programming is a
pleasant mix of both science and art. There's a certain aesthetic about a
well written function that also looks good. Of course, code beauty is in
the eye of the beholder.

OS5.2: has SysNotifyBroadcastFromInterrupt WakeupHandler been fixed ?
Hi all.
I'm stumped by a problem with OS 5.0 where the PACE environment in that OS
does not support SysNotifyBroadcastFromInterrupt() and is inconsistent with
a serial wakeup handler (set by SrmSetWakeupHandler). (See copy below of an
FAQ taken from the PalmSource KnowledgeBase that details this problem.) As
far as I can see I need both these functions for my application to function
properly.
My question is: Does anyone know if the SysNotifyBroadcastFromInterrupt() is
supported in OS 5.2?
Also can someone confirm that the interrupt-driven wakeup handler is fully
functional in OS 5.2 as claimed in the FAQ.
I'd appreciate any help on this at all since I don't want to invest in a
OS5.2 device if it's not going to work. Thanx
Steve
PS. Do you know if the latest version of the OS 5 Simulator for Windows can
now handle interrupt-driven wakeup handlers?

Question:
Palm OS 5 applications may have trouble running at interrupt time
Answer
The Palm Application Compatibility Environment (PACE) is not interrupt safe
so 68K applications running through PACE may experience problems if they
attempt to run during an interrupt. A couple of ramifications of this are:
1) SysNotifyBroadcastFromInterrupt is non existent through PACE in Palm OS
5. Developers should check the OS version before they attempt to make this
call.
2) Serial Wakeup Handlers set with SrmSetWakeupHandler may work
inconsistently under different versions of OS 5 and will not work at all via
the Palm OS 5 Simulator. In general, developers should avoid using serial
wakeup handlers in OS 5.
**If you do attempt to use wakeup handlers in an OS 5.0 environment note
that they will only work while the application that set the wakeup handler
is still active. This is fixed in OS 5.2, but the wakeup handler itself
should be stored in a memory location separate from the application (such as
copying the function into a FtrPtr and setting the wakeup handler to this
FtrPtr). For example:
//The size of the handler function can be calculated by subtracting the
memory location //of the handler function from the next function in your
code resource. sizeOfPatch = (UInt32)((UInt32)FunctionAfterHandler-
(UInt32)HandlerFunction);
//allocate a FtrPtr the size of our handler and then copy it in.
FtrPtrNew(appFileCreator, ourFuncFeature, sizeOfPatch, funcP); if (funcP)
{ //copy callback function to the above address. DmWrite(funcP, 0,
(MemPtr)HandlerFunction, sizeOfPatch); }

Well, although completely illegal it works. Why would CodeWarrior allow
me to perform such a haneous action if it was that bad.

through?
I've been meaning to get a better understanding of pointers, I'm kinda
running gunning
it, learning as I go... which I know would make some programmers cringe,

Okay, this a bit of a dorky question. I asked at a C Forum, and this

It is a C issue, although the error message you get is a bit nicer than
the error message you might get from another OS.
typedef struct
{
UInt32 *orderQty;
Char *key;
Char *desc;
} OnOrder;
onOrder.orderQty = (UInt32 *) StrAToI(FldGetTextPtr(field));
// Gets the number from the field
This is not such a good idea because StrAToI doesn't like NULL pointers,
and if the user has never entered something into the field, then it will
complain.
It's also completely illegal. What good is converting an integer into a
pointer going to do you?
UnpackOnOrder(onOrderFound, packedOnOrder); // Grabs from
pdb
*(onOrder.orderQty) += *(onOrderFound.orderQty);// THIS
LINE CAUSES THE ERROR
Well, since you did that bizarre assignment earlier, the value of
orderQty is whatever value was in the form. My guess is that it was 20,
since your error message was Application just read from memory location
0x14, and 0x14 == 20.
You should get a good book on C and programming with C pointers. If the
people on the C forum had read your code more carefully, they would have
seen the problem as well.

So, the wise thing to do would be to use the new only if you are sure you are not gonna need the object for longer periods of times. Guys, please correct me if I am wrong. You're wrong on this part. MemPtrNew allocates a non-movable chunk that is immune to compaction or defragmentation. MemHandleNew allocates a movable chunk that will be essentially flagged as non-movable when you lock it with MemHandleLock. It's perfectly safe to allocate long-lived pointers with new. The only thing is that it can cause memory fragmentation (this is generally true in any OS, but on small-memory systems it can be more of a problem). However, the same thing can be said if you allocate a handle and lock it for the length of the program. -- Dave Carrigan Seattle, WA, USA [EMAIL PROTECTED] | http://www.rudedog.org/ | ICQ:161669680 UNIX-Apache-Perl-Linux-Firewalls-LDAP-C-C++-DNS-PalmOS-PostgreSQL-MySQL -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Fw: Re: How know the name fields of PDB file
Thanks Doug for that explanation. And nice to see ya' after a long time. :-) No, things fell apart because you made the assumption the recordlist info would follow a 78 byte header. Per the Palm OS docs you need to account for the AppInfoBlock, if present, and the SortInfoBlock, if present. It is not AppForge's fault if you made false assumptions. Correct. But Doug, how would I know what all info is it dumping in the AppInfoBlock or SortInfoBlock ? I mean there is no way for me to know by how much do I have to increment my offset unless I know what all bytes have been dumped in there. One could simply put in some secret messages/easters etc in the above block and it would be just too much for my lil palm-based PDB reader. -Viren -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: new and delete in Palm
The 64K limitation I think is an arbitrary choice. If I recall correctly, the chunk header allows up to 16M chunks, but they limit it to 64K because the hotsync protocol only supports up to 64K record sizes. Palm OS 1.0 and 2.0 had memory heaps that were limited to 64K, so it wasn't actually possible to allocate a block of memory larger than that size. This heap structure was reworked in Palm OS 3.0, but the HotSync protocol wasn't fixed to support these large chunks. Palm OS 3.5 provided a back door to allocating large chunks, and this is used by the MemGluePtrNew call in the glue library included in Palm OS SDK 5.0 R2. -- Ben Combee [EMAIL PROTECTED] CodeWarrior for Palm OS technical lead Palm OS programming help @ www.palmoswerks.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: Low Memory - (Newbie Ques)
Where are you allocating memory that your orderQtr pointer will point to. I suspect that orderQtr should really be a UInt32, not a pointer to a UInt32. The same question goes for key and desc. Unless you allocate space somewhere in memory and stick a pointer to that space into the fields, you're dealing with unknown values. I think you need to read up on C pointers and string handling. This doesn't just apply to Palm OS but to any platform using C. Thanks Ben, actually I've been reading up at the CodeWarriorU site about C (as well as another C book) and such but haven't gotten to pointers yet.

Re: lists (how to change scrollbar look feel)
Draw the list and the scroll bar. Handle the scroll bar messages and update the list manually. Its not as hard as it sounds. If your app displays a scroll bar and handles the events, you can force the list to do whatever you want. As far as not displaying the list scroll arrows, you can set the list up with just enough lines to fill the screen once and handle tracking which items are visible/selected.

Does that the reason why any resource in Palm cannt be larger than 64K ? And thencannt I hide the physical addresses behind the handles ? I thought a handle is really a pointer to pointer. I particularly wanna know more on how does the system make up for lack of a typical MMU ? The Dragonball processor doesn't have a MMU, but the existence or lack of a MMU is not really related to how the PalmOS memory manager works. Grossly simplified, an MMU is used to map a memory address to some other address. This is useful in a multitasking OS so that each process thinks that its memory starts at address 0. The MMU takes care of mapping the process' virtual address to a real physical address. At a higher level, you still need something to manage the memory space so that when an app calls malloc, or MemHandleNew, or whatever (including indirect calls through the new operator), the app gets something, and when the app frees up the memory (via free, MemHandleFree, delete, etc.), the space is again marked as free. This is also a called a memory manager, but has nothing to do with the MMU. A memory chunk is just an arbitrary name that the PalmOS developers gave to a piece of memory that is managed by the PalmOS memory manager. Every OS call that allocates memory (MemPtrNew, MemHandleNew, MemHandleResize, DmNewRecord, DmResizeRecord, etc.) will eventually get a chunk that the memory manager has decided it can have.

RE: (Newbie) Howto send and receive files??
-Original Message-
From: Ricardo Marques
Sent: Wednesday, August 13, 2003 8:29 AM
For example, the user would go to the menu and press Send
File, after which a form would appear asking which file the
user would like to send and allowing to indicate it. How can
I do that? That is, how do i know where a file is stored
within the OS, how do I find it and select it to send, and
how do I save a received file in a location chosen by the user
This is a very common functionality and as such, there are helper APIs
that will save you a lot of time, Ricardo. You can get a list of all
files on the device with SysCreateDataBaseList(). For example:
-
MemHandle haItems = NULL; // Handle to array of SysDBListItemType
UInt16wNumDBsFound = 0; // # of SysDBListItemType items in
haItems
SysCreateDataBaseList( sysFileTApplication, 0, wNumDBsFound, haItems,
true );
-
Once haItems is generated, you can load up a list control with the
strings inside the SysDBListItemType.name member (see
http://tinyurl.com/jws9 for info on generating a list's contents during
runtime):
-
SysDBListItemType* paItems = NULL;
if ( haItems )
SysDBListItemType* paItems = (SysDBListItemType*) MemHandleLock(
haItems );
if ( paItems )
{
for ( UInt16 i = 0; i wNumDBsFound; i++ )
AddStringToMyList( paItems[i].name ); // Analogous to
FillListWithYears()
// in the List recipe URL
}
MemHandleFree( haItems ); haItems = NULL;
-
Once a user has selected one of the items from the listbox to beam, you
want to lock down haItems again, advance to the index corresponding to
the user's selection, extract its name, creator ID, and dbID, and then
use the Exchange Manager to send the file. BE SURE to MemHandleFree(
haItems ) at some point after you no longer need it, or else you will
leak the memory allocated to store the array.
See http://tinyurl.com/jwrd for sample code of how to send a database
using the Exchange Manager. The only thing I would add to this recipe
is to use one of the prefixes defined in http://tinyurl.com/jwr7 so that
your user is prompted whether they'd like to send (Bluetooth) or beam
(IR) or SMS the file, depending on the capabilities of the device on
which your app would be run.
See the bottom of http://tinyurl.com/jwrw for a sample WriteProc() that
should work for your ExgDBWrite() call.
I hope this gets you going. Be patient with the Exchange Manager, it
can be fickle, but once you've beamed a file through thin air, you
realize it was worth it. At least, I did.

No, I'm not. It's straight C.
Here is some psuedo-code. It's been years since I even compiled
my list builder code. It's in CVS someplace and I don't feel like

INCREDIBLE sum of 208 bytes of code space.

int amt=cnt*(sizeof(char*)+(listWidth+1));

}
If you want to get really ooky for no particular reason,
you can use handles and lock them.
and also violates the coding practice of trying to unallocate
memory from within the same function in which it was allocated.
You evidently have no experience with 'Lazy evaluation'.
Never heard of your 'coding practice'.
The fact is, if the global is not null, there is memory allocated to the list.
You need to de-allocate before allocating again. If you like, I'll
move the clause to a separate function, OK?
Your '??' on the setting of pListText to NULL makes me think
you don't get it;
Leaving the de-allocation of the prior list to the list builder
function is what makes memory handling simple. Any time you build
a list, it cleans itself.
I'm not
saying either way is wrong... Just offering reasons why some people choose
different methods.
What you *are* saying is that you don't have much experience with
allocating/deallocating memory for dynamic lists.

Aaron hasn't chimed in with advise on replacing all calls with MemMove,

Todd, as you can see, you're not heading down the right path. If you're
going to find it difficult to keep track of the type of pointer you're
dealing with, the legal way of handling your requirement is:
#define SafeUlgyDmWrite(a,b,c,d)
{MemPtrDataStorage(a)?DmWrite(a,b,c,d):MemMove(a+b,c,d);} /*Note - Untested
code... Use at you're own risk!!!*/
You can now use the aptly named SafeUlgyDmWrite to replace all your
DmWrites, and not care whether they're into Dynamic or Storage Memory.

RE: Breakpoint stopping code, But I removed it!
I fixed the problem - it's not the IDE, it was just coincidence that the line that I had the breakpoint on (the diffC =...) did not cause an error when you stopped on it, then continued, but failed miserably when run at full speed. The difference lies in the treatment of pointers. As far as I knew this should work (tho I can't recall ever doing it quite this way before): Int16 * NumberTimes1Ptr, * NumberTimes2ptr NumberTimes1Ptr = (Int16 *) ((UInt32)rec1 + FishStr1Len + 1); NumberTimes2Ptr = (Int16 *) ((UInt32)rec2 + FishStr2Len + 1); diffC = *NumberTimes1Ptr - *NumberTimes2Ptr; If this code, the computation of diffC would fail if either NumberTimes1Ptr or NumberTimes2Ptr were misaligned (on an odd address). Any 16-bit or 32-bit memory access on the 68K must be on an even memory boundary. It doesn't, at least not with CW9. The following code DOES work: Int16 NumberTimes1, NumberTimes2 NumberTimes1Ptr = (UInt8 *) ((UInt32)rec1 + FishStr1Len + 1); NumberTimes2Ptr = (UInt8 *) ((UInt32)rec2 + FishStr2Len + 1); MemMove(NumberTimes1,NumberTimes1Ptr,2); MemMove(NumberTimes2,NumberTimes2Ptr,2); diffC = NumberTimes1 - NumberTimes2; This works because you use MemMove to copy the values into aligned memory first. -- Ben Combee [EMAIL PROTECTED] CodeWarrior for Palm OS technical lead Palm OS programming help @ www.palmoswerks.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
RE: Replace Substrings
Subject: Replace Substrings
From: Jim Duffy [EMAIL PROTECTED]
Date: Thu, 7 Aug 2003 01:22:18 -0700
Does anyone know a way to search through a string for all instances of a
substring and replace them with a different substring?
For example:
string1 This[CR]is a [CR] Test
I need to replace all the [CR] with the '\n' newline character..
I've tried using StrStr() and TxtReplaceStr() but these aren't really cut
out for this. Can't find any other API that might work..
Your example is character replacement, which can be achieved by:
// substitute Char c1 with Char c2
Char *ptr = string1;
while ((ptr = StrChr (ptr, c1)) != NULL) {*ptr = c2; ptr++;}
For substring substitution in-situ, you can use:
// Substitute Char *str1 with Char *str2, using shortest length
Char *ptr = string1;
UInt16 len = (StrLen (str1) StrLen (str2) ? StrLen (str2) : StrLen (str1));
while (len (ptr = StrStr (ptr, str1)) != NULL) {
StrNCopy (ptr, str2, len):
ptr += len;
}
Fully handling substrings of unequal size is a tricker because you have to
make a copy of the original string and copy it back to the original string
in segments, inserting the new string as appropriate. Someone else
provided an example of that.

Re: LstGetSelectionText() - Memory Allocation ?!?!
I doubt they'll every add it, since the existing API is capable of doing the job. Besides that, it's possible to simulate a text callback using the existing API.. Simply use the userDataP to hold your function pointer, then you only need to write one ListDraw function (which then calls your text callback). Easy huh?.. Take about 15 minutes to write it the first time, stick it into your standard library code, get the exact functionality you need, and it only adds 10 lines of code to your whole project. Alan James [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I really, really wish Lists could have an application-defined callback to retrieve the text for a specified item. Here's how I envision it would work: typedef Char* (*ListGetSelectionTextFuncType)(const ListType* listP, Int16 itemNum, void* userDataP); void LstSetListChoices(ListType* listP, Char** itemsText, Int16 numItems, ListGetSelectionTextFuncType getTextFunc, void* userDataP); getTextFunc would be optional; if NULL, all Lst functions would try to retrieve strings directly from itemsText. The advantage of this system would be that: 1. there's less need to use a custom drawing function; I'd bet that most lists with custom-drawn items are purely textual, so the system now could draw the list items itself 2. when dealing with pop-up triggers to such lists, the system could update the trigger label itself 3. it would allow incremental-search to be used with such lists (While I'm wishing, I wish you could set a callback for a pop-up list's event handler too.) #3 is the most important to me. 1 and 2 are not that much extra work with the current system, but the combination of incremental-search's dependence on a valid itemsText pointer and the lack of ability to set your own list event handler makes it really hard to implement 3 yourself. Currently if you want incremental-search with a dynamically generated list, it's easiest to make copies of all your strings and suffer the additional memory usage. Obviously there's not much that can be done about this for existing versions of Palm OS, but hopefully this stuff can be changed for Palm OS 6 if it hasn't been already... __ Do you Yahoo!? Yahoo!

It has to be in the corresponding Windows code page, which is what Palm devices typically use for their charset. So if you're doing Big-5, then the input text is CP950 (basically Big-5), and so on. How do I tell pilrc which characterset I used to=20 }encode my rcp file... Or is it always a certain format and=20 }some escape sequences. In Java for example you can encode=20 }unicode characters like so: \ua0b0 (unicode character 0xa0b0). Check out the pilrc manual's description of the -Fwhatever command line parameter. For example -F5 for Big-5, -Fg for GB. Based on this setting, pilrc assumes that the input file uses the corresponding character encoding. -- Ken -- Ken Krugler TransPac Software, Inc. http://www.transpac.com +1 530-470-9200 -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

RE: Coding Standards
That's close to mine. Personally, I'd have it as:
void MyFunc(Char* buffer, UInt32 type)
{
switch(type)
{
case 1:// This is an example with braces.
{
StrCopy(buffer, One);
break;
}
case 2:// This is an example without braces.
StrCopy(buffer, Two);
break;
default:
StrCopy(buffer, Huh?);
break;
}
}
That is: braces always line up, and use 4-space TABs (I'm using spaces above since not
all email programs expand TABs the way I'd like them).
I hate the way MS lines the case statement under the switch statement.

Re: The PalmOs command line accept arguments for applications?
NormalLaunch doesn't accept arguments, but some PalmOS applications support other custom launch codes which allow an argument parameter block to be passed in. Indeed, which is why I suggested he look at launch codes :-) And there are a few 3rd party utility applications which will allow one to insert CmdGoto parameters on a command line. That's just confusing the issue isn't it? :-) There is not a command line in the PalmOS in the sense that there is in most desktop OSes. He needs to learn about launch codes.

Yes, for good reason. The emulator is designed to catch a lot of bugs
in your code that may not cause problems the device you happen to have
right now, but might cause problems on other devices or other versions
of PalmOS. A well-written app will not trigger any errors from the
emulator.

Re: Codewarrio stack usage with temporaries
At 02:30 PM 8/8/2003, Todd Niec wrote: How does code warrior handle stack usage for unamed temporary variables? I have a procedure that creates lots of unnamed temporary variables as a result of conversion operators. I can see that, in terms of constructors and destructors, these temporaries are being created and destroyed as the function executes, but the stack usage steadily increases and increases as the function executes. Eventually I run out of stack space. CW allocates all temporaries on the stack at function entry time. However, there is a case where your stack usage can increase while your function is running -- the compiler defaults to deferring cleanup of the stack used for argument passing. If you've got a loop with a function call, using #pragma stack_cleanup on will cause the compiler to remove items from the stack as soon as a function returns. -- Ben Combee [EMAIL PROTECTED] CodeWarrior for Palm OS technical lead Palm OS programming help @ www.palmoswerks.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: newbie question: how to read a string from a MemHandle?
I'm not sure what you are doing wrong. As I see it to write the data to the

MemHandle h = NULL;
// Append data to whatever is already in handle
void WriteDataToHandle(Char *dataInP)
{
Char *strP;
Err err;
UInt16 len = StrLen(dataInP);
if (!h)
{
h = MemHandleNew(len+1);
if (h)
{
strP = (Char *)MemHandleLock(h);
if (strP)
{
StrCopy(strP, dataInP);
MemHandleUnlock(h);
}
}
}
else
{
err = MemHandleResize(MemHandleSize(h)+(len+1));
if (!err)
{
strP = (Char *)MemHandleLock(h);
if (strP)
{
// Append data
StrCat(strP, dataInP);

}
}
}
