pub struct Epoll<Context: Context> { /* private fields */ }
Expand description

An “epoll”, an interface to an OS object allowing one to repeatedly wait for events from a set of file descriptors efficiently.

Implementations

epoll_create1(flags)—Creates a new Epoll.

Use the CreateFlags::CLOEXEC flag to prevent the resulting file descriptor from being implicitly passed across exec boundaries.

epoll_ctl(self, EPOLL_CTL_ADD, data, event)—Adds an element to an Epoll.

This registers interest in any of the events set in events occurring on the file descriptor associated with data.

epoll_ctl(self, EPOLL_CTL_MOD, target, event)—Modifies an element in this Epoll.

This sets the events of interest with target to events.

epoll_ctl(self, EPOLL_CTL_DEL, target, NULL)—Removes an element in this Epoll.

This also returns the owning Data.

epoll_wait(self, events, timeout)—Waits for registered events of interest.

For each event of interest, an element is written to events. On success, this returns the number of written elements.
