tracking forks/execs is an old problems...some debuggers I understand
handle this acceptably...
This trick works:
#if 1
/* harmless -- trap fork on an environment to attach debugger */
static int fork_debug(void)
{
int result;
result = fork();
if(result == 0 && getenv("FORKDEBUG")) {
printf("Child is %d, stopped\n", getpid());
pause();
}
return result;
}
#define fork fork_debug
#endif
Different OSes need different variants of the pause() -- SunOS works
transparently...
You can put a printf/pause in the target program right after main
it is execed...
