Hi,
I'm traying to debug a fork()-ing process, and according the GDB manual pages
setting the 'follow-fork-mode' to 'child' will cause to switch to children.
So this could be the case if I'm attached to some process in GDB but in case
that I'm debugging the master application I'm always staying in parent
process.
Here are the details :
bash-2.04$ uname -a
FreeBSD yo.rila.bg 4.6-STABLE FreeBSD 4.6-STABLE #1: Thu Oct 10 15:39:15 EEST
2002 root@yo.rila.bg:/usr/obj/usr/src/sys/YO i386
$ gdb blah
(gdb) set follow-fork-mode child
Debugger response to a program call of fork or vfork is "child".
(gdb) n / several times to reach the fork() call /
428 pid = fork();
(gdb)
429 if (pid != 0) {
(gdb) p pid
$2 = 12886
(gdb)
Any comments would be greatfuly appreciated.
