close
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
