Constant nc::types::EPOLLWAKEUP

pub const EPOLLWAKEUP: poll_t

Request the handling of system wakeup events so as to prevent system suspends from happening while those events are being processed.

Assuming neither EPOLLET nor EPOLLONESHOT is set, system suspends will not be re-allowed until epoll_wait is called again after consuming the wakeup event(s).

Requires CAP_BLOCK_SUSPEND
