Hi,
I'm traying to debug a fork()-ing process, and according the GDB manual p=
ages=20
setting the 'follow-fork-mode' to 'child' will cause to switch to childre=
n.=20
So this could be the case if I'm attached to some process in GDB but in c=
ase=20
that I'm debugging the master application I'm always staying in parent=20
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=20
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 =3D fork();
(gdb)
429 if (pid !=3D 0) {
(gdb) p pid
$2 =3D 12886
(gdb)
Any comments would be greatfuly appreciated.
