@ -96,9 +96,11 @@ The module defines the following:
.. attribute:: select.PIPE_BUF
Files reported as ready for writing by :func:`select`, :func:`poll` or
similar interfaces in this module are guaranteed to not block on a write
of up to :const:`PIPE_BUF` bytes.
The minimum number of bytes which can be written without blocking to a pipe
when the pipe has been reported as ready for writing by :func:`select`,
:func:`poll` or another interface in this module. This doesn't apply
to other kind of file-like objects such as sockets.
This value is guaranteed by POSIX to be at least 512. Availability: Unix.
