Hi,
I have the following program that attaches and detaches to/from a process
and it works on other unixes but on FreeBSD it just kills the
process right after
attaching to it. I tried it on 3 differend boxes and the result is the
same. Is there something specific about FreeBSD ? gdb doesn't fail so i
guess I'm misssing something even though it is a 10 lines program.
Please reply to boyan@ixc.net because I'm not on the list.
Thanks

int result;
pid_t pid;
caddr_t addr;
void main() {
pid = 29282;
addr = 0;
result = ptrace(PT_ATTACH, pid, addr, 0);
result = ptrace(PT_DETACH, pid, addr, 0);
}
