    <title>Description</title>
<para>This function can be used to turn a Win32 "handle" into a
posix-style file handle. <parameter>fd</parameter> may be -1 to
make cygwin allocate a handle; the actual handle is returned
in all cases.</para>

<para>Even after using function, Cygwin doesn't know anything about the
underlying file or device.  It just tries to supply the typical file
functions on a "best-effort" basis.  Use with care.  Don't expect too
much.</para>
