Noop, just verified it again
on FBSD 4.4 STABLE, this:
int
process_alive(pid)
pid_t pid;
{
while (waitpid(pid, NULL, WNOHANG) < 0 && errno == EINTR)
/* do nothing */;
return kill(pid, 0) == 0;
}
misses a bunch of closed? deleted? usd up pids?
on my client, it stays in 'SMB use SID to enemurate'
but i verified these are not still runnning.
only one that works is this code:
/*
* Invalid argument
*/
if(!pid)
return 0;
*/
for(i=0,ret=1;(i<100) && (ret > 0);i++)
ret = waitpid(pid, NULL, WNOHANG);
return kill(pid, 0) == 0;
