示例1: poll_out
// poll for writing

{
#ifndef _WIN32
struct pollfd pollset[1];
pollset[0].fd = sockfd;
pollset[0].events = POLLOUT|POLLERR;

int result = ::poll(pollset, 1, timeout.msec());
if (result > 0)
return pollset[0].revents;
else
return result;
#else
fd_set fds_write, fds_err;
FD_ZERO(&fds_write);
