poll(NULL, 0, t)

[Adek336]

#include <poll.h>
#include <stdio.h>

int main()
{
       int i = poll(NULL, 0, 2000);
       fprintf(stderr, "%d\n", i);
       return 0;
}

Haiku: immiedately prints -1 Linux, FreeBSD: sleeps for 2 seconds and prints 0

This program passes fds = NULL but at the same time, nfds = 0; so there isn't any actual null pointer dereference. The docs ​http://www.opengroup.org/onlinepubs/007908799/xsh/poll.html don't seem to cover this issue. I guess Haiku should follow the standard undocumented behaviour.
