Function epoll_wait [src]

Waits for an I/O event on an epoll file descriptor. Returns the number of file descriptors ready for the requested I/O, or zero if no file descriptor became ready during the requested timeout milliseconds.

Prototype

pub fn epoll_wait(epfd: i32, events: []system.epoll_event, timeout: i32) usize

Parameters

epfd: i32events: []system.epoll_eventtimeout: i32

  pub fn epoll_wait(epfd: i32, events: []system.epoll_event, timeout: i32) usize {
    while (true) {

        const rc = system.epoll_wait(epfd, events.ptr, @intCast(events.len), timeout);
        switch (errno(rc)) {
            .SUCCESS => return @intCast(rc),
            .INTR => continue,
            .BADF => unreachable,
            .FAULT => unreachable,
