When you setup a signal handler, pass the SA_SIGINFO in the sigaction flags. Where can I find the description of the the stack frame passed to a sigaction handler by the OS? The stack frame looks like this on Linux, I'm looking for same on Leopard. Thanks in advance! This email sent to site_archiver(a)lists.apple.com

It's nowhere documented (nor guaranteed to remain compatible among different versions). There's however some sample code which never was updated for i386 as part of the MoreIsBetter sample: http://developer.apple.com/samplecode/MoreIsBetter/listing83.html These people did update it for i386 and did some other fixes (and got ahold of a newer version somehow): http://boinc.berkeley.edu/trac/browser/trunk/boinc/lib/MoreBacktrace.c?rev=… The latter code is LGPL though, so depending on your licensing requirements you may or may not want to look at it.

Re: full path to the currently running executable

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… _NSGetExecutablePath() copies the path of the main executable into the buffer buf. The bufsize parameter should initially be the size of the buffer. This function returns 0 if the path was successfully copied. It returns -1 if the buffer is not large enough, and * bufsize is set to the size required. Note that _NSGetExecutablePath() will return "a path" to the executable not a "real path" to the executable. That is, the path may be a symbolic link and not the real file. With deep directories the total bufsize needed could be more than MAXPATHLEN. It's possible to get the full path to the currently running executable on Linux by looking at /proc/self/exe or /proc/curproc/ file. This email sent to site_archiver(a)lists.apple.com
