SYNOPSIS

       #include <ieee1284.h>


       int ieee1284_claim (struct parport *port);

DESCRIPTION

       With  the exception of ieee1284_get_deviceid(3), ieee1284_claim must be
       called on an open port before any other libieee1284  function  for  ac-
       cessing a device on it.

RETURN VALUE

       E1284_OK
              Success.  Note that, unless the F1284_EXCL flag was specified to
              start with, the port should be released within a  ``reasonable''
              amount of time.


       E1284_NOMEM
              There is not enough memory.


       E1284_INVALIDPORT
              The  port  parameter is invalid (for instance, it might not have
              been opened yet).


       E1284_SYS
              There was a problem at the operating system  level.  The  global
              variable errno has been set appropriately.
