You are responsible for opening and close the file descriptor. This allows you to use Pexpect with sockets and named pipes (FIFOs). .. note:: socket.fileno() does not give a readable file descriptor on windows. Use :mod:`pexpect.socket_pexpect` for cross-platform socket support PEXPECT LICENSE This license is approved by the OSI and FSF as GPL-compatible. http://opensource.org/licenses/isc-license.txt Copyright (c) 2012, Noah Spurrier <noah@noah.org> PERMISSION TO USE, COPY, MODIFY, AND/OR DISTRIBUTE THIS SOFTWARE FOR ANY PURPOSE WITH OR WITHOUT FEE IS HEREBY GRANTED, PROVIDED THAT THE ABOVE COPYRIGHT NOTICE AND THIS PERMISSION NOTICE APPEAR IN ALL COPIES.

The read_nonblocking method of :class:`SpawnBase` assumes that a call to os.read will not block (timeout parameter is ignored). This is not the case for POSIX file-like objects such as sockets and serial ports. Use :func:`select.select`, timeout is implemented conditionally for POSIX systems. :param int size: Read at most *size* bytes. :param int timeout: Wait timeout seconds for file descriptor to be ready to read.
