[Python module] select

16.1. select — Waiting for I/O completion¶
This module provides access to the select and poll functions available in most operating systems, epoll available on Linux 2.5+ and kqueue available on most BSD. Note that on Windows, it only works for sockets; on other operating systems, it also works for other file types (in particular, on Unix, it works on pipes). It cannot be used on regular files to determine whether a file has grown since it was last read.
The module defines the following:
