 \indexii{UNIX@\UNIX{}}{I/O control}
 
 This module performs file control and I/O control on file descriptors.
-It is an interface to the \dfn{fcntl()} and \dfn{ioctl()} \UNIX{} routines.
-File descriptors can be obtained with the \dfn{fileno()} method of a
-file or socket object.
+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.
 
 The module defines the following functions:
 
-\setindexsubitem{(in module struct)}
 
-\begin{funcdesc}{fcntl}{fd\, op\optional{\, arg}}
-  Perform the requested operation on file descriptor \code{\var{fd}}.
-  The operation is defined by \code{\var{op}} and is operating system
+\begin{funcdesc}{fcntl}{fd, op\optional{, arg}}
+  Perform the requested operation on file descriptor \var{fd}.
+  The operation is defined by \var{op} and is operating system
   dependent.  Typically these codes can be retrieved from the library
-  module \code{FCNTL}. The argument \code{\var{arg}} is optional, and
+  module \module{FCNTL}. The argument \var{arg} is optional, and
   defaults to the integer value \code{0}.  When
   it is present, it can either be an integer value, or a string.  With
   the argument missing or an integer value, the return value of this
-  function is the integer return value of the real \code{fcntl()}
+  function is the integer return value of the \C{} \cfunction{fcntl()}
   call.  When the argument is a string it represents a binary
-  structure, e.g.\ created by \code{struct.pack()}. The binary data is
-  copied to a buffer whose address is passed to the real \code{fcntl()}
-  call.  The return value after a successful call is the contents of
-  the buffer, converted to a string object.  In case the
-  \code{fcntl()} fails, an \code{IOError} will be raised.
