I don't think there's a way currently. What I did in my local tree is modify kern_kevent so that if the magic number -1 is passed in as nchanges, it will return the entire queued event list back to the caller in *eventlist, and return the number of events as the returncode. Very useful for debugging kqueue-using programs where you want to compare what you think you're waiting for, and what the kernel thinks you're waiting for :) Why does this pop in my mind when reading your reply? :) Lt. Saavik: You lied. Spock: I exaggerated. In other words, there does not currently exist a method to does this on a vanilla system. I can deal with that. It still would be a nice feature to have.

I was working with it recently and my understanding is that if you want to retrieve any events and not block if there are none then you should give it zeroed struct timespec. Quote from the man page: "If timeout is a NULL pointer, kevent() waits indefinitely. To effect a poll, the timeout argument should be non-NULL, pointing to a zero-valued timespec structure." I understand about the timeout. I am looking for different methods to break out of a loop where I want to remain until all events are handled and deleted from the kqueue.

Besides tracking what events are still within a kqueue, this would make for an easier way to write an event loop. Currently, calling kevent() on an empty kqueue will still block. Why do you need this? What is the point of calling kevent if you don't have an event to wake it up? Can you give us an example of where you need to know that there isn't any events in the queue? (I can't think of one, since using kqueue w/o events is pointless.) I can't see how tracking the count will let you know which events are still in the kqueue... (second to last sentence) If you register a number of events to be handled by a single kevent-loop and they are deleted (by kevent() or EV_ONESHOT), it would be nice for a way to see if there are any more kevents registered in the kqueue when deciding to exit the loop (or program) or performing some special operation when all events are gone. Also, I recommend that the man page mention that a kqueue may be close(2)'d. The only reference that it can be is that the manual page says the kqueue() call returns a descriptor. I would think that it would need to be documented when you can't close a descriptor.. Neither pipe nor socketpair documents that close can be called on them... Good point. It was just a thought for us beginners to kevents. The other calls have a multitude of sources for documentation.

It had happened before I started trying to fix the size problem described above. After slicing the newly created RAID 0 array with sysinstall and installing Windows, formatting NTFS and FAT slices (with Windows) I created BSD partitions on the first slice and lost the extended partition (slice). (a more detailed description of what I did is in the original posting to freebsd-questions). Today, after the change in kernel, I have removed FreeBSD partitions from the first slice and recreated them (with some differences). Nothing wrong happened. Could this be connected with the bug in VIA ata raid driver? Or maybe it was just a coincidence and/or was entirely my fault? With the partition corruption (all of them) in a slice I reported[1] to stable@ with the same controller, I think I smell a bug. I do not know if it is a VIA hardware bug or a bug in the driver.

Re: Vertikal and Horizontal Scroll of (mighty) mice

I fixed this by teaching ums.c to prefer WHEEL over Z but it would be nice to support both wheel and z axis scrolling. I checked the mouse(4) but the dataformat there does not even support a forth axis. Hacking ums.c to map z axis to buttons 7 and 8 would be possible, but not a clean solution. Another Option would be to add a z2 axis or something tothe SYSMOUSE format. What are your opinion? I have an MX1000[1] from Logitech with many buttons and a wheel. The wheel can scroll up and down and "click" left and right. The PS/2 driver did not support enough of its buttons which caused moused to not see all of the buttons. I recommend looking at this first link since it details one way of setting up a mouse with many buttons. I used the ums driver, but I had to enable more buttons in the driver[2]. You may need that patch to use it fully, but I do not know how many logical buttons you have. In X, you will need to configure the mouse with xmodmap. Here is my line to my mouse to do most of what I want. It moves the paste action to the button above the wheel instead of the click of the wheel. xmodmap -e "pointer = 1 7 3 9 10 6 2 8 4 5 11 12" Here is the mouse in xorg.conf: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/ums0" Option "Buttons" "12" Option "Emulate3Buttons" "false" Option "ZAxisMapping" "9 10" EndSection Seán 1. http://floam.sh.nu/index.xhtml?page=guides§ion=mx1000 2. http://www.freebsd.org/cgi/query-pr.cgi?pr=usb/83353 -- [EMAIL PROTECTED]___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: Using a logitech mx700 with scrollwheel _and_ thumb buttons
On Wed, 6 Jul 2005, Julian Elischer wrote: Joe Schmoe wrote: Nope. I reproduced these same settings _exactly_, and they produce the same results. With your settings above, the scroll wheel works fine, and the two thumb buttons each cause the web page to scroll very slightly downward. This is the same thing they did with all the other different configurations I tried. Why is using mouse thumb buttons under FreeBSD _rocket science_ ? Why is this a _hard problem_ ? because no-one who has the interest in fixing it has the time to do so and visa versa. I do not know how to fix it using the psm driver, but here is what I did with the Logitech MX 1000 I bought over the weekend. I tried using the psm driver, but it claimed a maximum of seven buttons while this mouse has twelve according to one source[1]. I then tried the ums driver, yet it also claimed only seven buttons. Fortunately, I found a NetBSD PR (kern/30248 [2]) concerning the button limit in the ums driver. Since sc_buttons is an int, I just bumped up MAX_BUTTONS to 31, and the driver found 16 buttons. xorg.conf mouse section: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/ums0" Option "Buttons" "12" Option "Emulate3Buttons" "false" Option "ZAxisMapping" "9 10" EndSection Although I disabled the moused loading in /etc/usbd.conf to allow X to capture the device, moused may still work. I doubt it, but is there a way to disable a particular check via rc.conf? With the following xmodmap command, I have a fair amount of the mouse working: xmodmap -e "pointer = 1 2 3 9 10 6 7 8 4 5 11 12" Problems: 1. psm has a limit to the number of buttons detected. I noticed this when I used moused in debug mode to see what events were thrown from the mouse. 2. The wheel pushed to the left and right does not work. It does not show up in xev. I may need to play with xorg.conf some more. 3. I need to find a way to disable Logitech's "Cruise Control" since I want to use the scroll up button above the wheel as the paste button. Cruise Control send the button number I want (7) plus a continuous stream of the button number (4) related to the wheel. I hate pasting with a wheel; I am almost always screwing something up during the paste due to slipping on the wheel. :) 4. I have no idea what the (magic number) button positions in xmodmap correspond with. I.e., 2 means paste, but what does 4 and on mean? Would anyone like to up the MAX_BUTTONS define in ums.c to a higher number, please?

The first condition poses no problem, just don't include the relevant ifconfig_ifn line in /etc/rc.conf and the interface won't be configured. But rc.d/dhclient and rc.d/netif won't work without an ifconfig line for the interface. Adding the ifconfig line and then listing every interface but the one I want configured in network_interfaces does prevent it from being configured at boot while having an ifconfig line in rc.conf, but if I try to use rc.d/netif to start the interface, rc.d/netif does nothing because it tests the interface against the contents of network_interfaces and cloned_interfaces, so the interface I left out will be excluded. Have I overlooked an option somewhere? What happens if you configure the interface in 'down' state, like : ifconfig_fxp0="inet 192.168.0.10 netmask 0xff00 down" Then rc.d/dhclient won't work. The "DHCP" keyword must be present in the ifconfig line in order for dhcpif to test true. A similar logic is in place for wpaif based on the "WPA" keyword. I am not sure it will help, but have you tried playing with /etc/start_if.DEVICE scripts? I do not know where they are documented, but you can configure a network device this way. I used it in the past to change the MAC address on a NIC at boot before the card was configured in rc.conf.

I'm about to undertake a major software engineering project and I can't decide between C or C++ and was wondering if I could get some input from the community. As part of this project I'm going to need to make use of at least 2 C libraries (OpenSSL and ncurses) and the application must be compatible with the standard range of Linux/UNIX compilers and operating systems. All of these signs make me sway closer to just doing it in C. However, one strong point always seems to pull me back to C++, constructors and destructors. Constructors and destructors can offer so much in the way of memory leak avoidance. Of course, each language can leak memory like a sieve if used improperly. However, for statically allocated structures semi-automatic garbage collection can be a nice cushion. Anyway, without getting into too much detail. Anyone had to make this choice on a project? What were your thoughts in retrospect? What would you have done different, what would stay the same... PS For this project things like polymorphisms and inheritance really aren't needed. If you would like to use C but want some sort of memory handling, I can recommend using the Apache Portable Runtime (APR) in /usr/ports/devel/apr which uses memory pools. Although I have not used it before, there is also the Boehm Garbage Collector found in /usr/ports/devel/boehm-gc.
