hello good day.
i have a question about the select()
function.
when should we set timeout parameter
into NULL? what is the difference of
putting timeout (0, 0) OR putting NULL
as parameter?

while(1) {
tv.sec = 0;
tv.usec = 0;
sel = select(fd+1, &rdfd, NULL, NULL, &tv);
}

while(1) {
sel = select(fd+1, &rdfd, NULL, NULL, NULL);
}

thanks a lot.
