Someone described this earlier, but I'll try to make it a bit more
clear. In the child, do something like this:
int main(void) {
static int foo = 0;
while (foo == 0) {
sleep(1);
}
...
}
That'll cause the child to spin on startup. Attach with gdb, type
'p (foo = 1)' at the gdb prompt, and then go from there.
Yeah, it's more complicated than that. I basically have to do that in
the child AND the parent, because the parent will time out in the
time it takes me to do all that for the child. (Also, keep in mind
that the child begins to execute on the return from fork(), not at
main).
If I do go to all this trouble, will I get to debug the child in the
GUI debugger, or will I have to do everything from the gdb command line?
