I'm looking at the poll()
man page, and it tells me the behavior of poll()
when positive and negative values are passed in for the timeout parameter. It doesn't doesn't tell me what happens if timeout is 0
. Any ideas?
Looking at the epoll_wait()
man page, it tells me that with a timeout value of 0
, it will return right away, even if there are no events available. Is it safe to assume that poll()
would behave the same way?
