Thanks, -Garrett Did a bit more poking around and determined how to do it. It wasn't core dumping because I didn't set the maximum limit for the coredump size to unlimited (ulimit -c unlimited).

See gcore(1) and abort(3). sysctl -a | grep core might turn up some interesting sysctls. -- /\ Best regards, | [EMAIL PROTECTED] \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | [EMAIL PROTECTED] / \ ASCII Ribbon Campaign | Against HTML Mail and News pgp7Tja5B2ZqY.pgp Description: PGP signature

Some signals default action is to cause the program to dump core, when they're delivered. You can see the list in the signal(3) man page. libc also provides the abort(3) function, which does what you want. The code is here: /usr/src/lib/libc/stdlib/abort.c Cheers, Vik -- PGP Key: 0xE09DC8D8/6799 4011 EBDE 6412 05A1 090C DBDF 5887 E09D C8D8 Signed/encrypted mail welcome! pgpXtluuOBwyC.pgp Description: PGP signature

Thank you all, the information I've gotten recently is definitely educational and it'll probably end up being useful later! -Garrett ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
