This is a straightforward interface to the Unix :cfunc:`select` system call.

The first three arguments are sequences of 'waitable objects': either

integers representing file descriptors or objects with a parameterless method

named :meth:`fileno` returning such an integer. The three sequences of
|

waitable objects are for input, output and 'exceptional conditions',

respectively. Empty sequences are allowed, but acceptance of three empty
|
||||
sequences is platform-dependent. (It is known to work on Unix but not on
|
||||
Windows.) The optional *timeout* argument specifies a time-out as a floating
|
||||
point number in seconds. When the *timeout* argument is omitted the function

blocks until at least one file descriptor is ready. A time-out value of zero
