Synopsis:
$close(<file descriptor>)
Technical:
This function unbinds the given file descriptor (previously returned by
the $open() function) from the underlying file, causing the file to be
committed to disk if necessary. An error is returned if it is passed a
file descriptor not produced by an $open() call.
Practical:
This function is used to close a file that was opened for reading or
writing by $open(). Data corruption may result if the client exits
before all open files are closed.
Returns:
-1 error
0 file closed successfully
