Added embryonic description of fcntl.lockf(). Added pointer to that 

in posixfile (which is obsolescent).

\code{fcntl()} calls. See the Unix manual for details.

If the library modules \code{FCNTL} or \code{IOCTL} are missing, you
can find the opcodes in the C include files \code{sys/fcntl} and
\code{sys/ioctl}. You can create the modules yourself with the h2py

\bimodindex{posixfile}
\indexii{posix}{file object}
\emph{Note:} This module will become obsolete in a future release.
The locking operation that it provides is done better and more
portably by the \code{fcntl.lockf()} call.
This module implements some additional functionality over the built-in
file objects. In particular, it implements file locking, control over
the file flags, and an easy interface to duplicate the file object.
