 This module performs file control and I/O control on file descriptors.
 It is an interface to the \cfunction{fcntl()} and \cfunction{ioctl()}
-\UNIX{} routines.  File descriptors can be obtained with the
-\method{fileno()} method of a file or socket object.

+All functions in this module take a file descriptor \var{fd} as their

-If the library modules \module{FCNTL}\refstmodindex{FCNTL} or
-\module{IOCTL}\refstmodindex{IOCTL} are missing, you can find the
