示例1: select
// Demultiplexing the I/O events
// Must be called in the loop thread.
int KqueueSelect::select(int timeout, WatcherList *activeList) {
int ret = -1;
ret = kevent(_kqueuefd, NULL, 0, _events, _evSize, NULL);
if (ret == -1)
{
// EINTR indicates epoll_wait was interrupted by a signal handler before
// any of the requested events occurred or the timeout expired.
if (errno != EINTR)
{
return -1;
}
return 0;
}
// Check what of the reqeusted events occurred on the file descriptors.
for (int i = 0; i < ret; ++i)
{
Watcher *w = (Watcher *)_events[i].udata;
int events = 0;
int filter = _events[i].filter;
if (filter == EVFILT_READ)
