fdpexpect - use pexpect with a file descriptor¶
This is like pexpect, but it will work with any file descriptor that you pass it. You are reponsible for opening and close the file descriptor. This allows you to use Pexpect with sockets and named pipes (FIFOs).

fdspawn(fd, args=None, timeout=30, maxread=2000, searchwindowsize=None, logfile=None, encoding=None, codec_errors='strict')¶
This is like pexpect.spawn but allows you to supply your own open file descriptor. For example, you could use it to read through a file looking for patterns, or to control a modem or serial device.
__init__(fd, args=None, timeout=30, maxread=2000, searchwindowsize=None, logfile=None, encoding=None, codec_errors='strict')¶
This takes a file descriptor (an int) or an object that support the fileno() method (returning an int). All Python file-like objects support fileno().
This checks if the file descriptor is still valid. If
os.fstat()does not raise an exception then we assume it is alive.
Close the file descriptor.
Calling this method a second time does nothing, but if the file descriptor was closed elsewhere,
OSErrorwill be raised.
