polling

polling

Portable interface to epoll, kqueue, event ports, and IOCP.

Supported platforms:

• epoll: Linux, Android, RedoxOS
• kqueue: macOS, iOS, tvOS, watchOS, visionOS, FreeBSD, NetBSD, OpenBSD, DragonFly BSD
• event ports: illumos, Solaris
• poll: VxWorks, Fuchsia, HermitOS, other Unix systems
• IOCP: Windows, Wine (version 7.13+)

By default, polling is done in oneshot mode, which means interest in I/O events needs to be re-enabled after an event is delivered if we're interested in the next event of the same kind. However, level and edge triggered modes are also available for certain operating systems. See the documentation of the PollMode type for more information.

Only one thread can be waiting for I/O events at a time.
