NAME
       ieee1284_claim - claim access to the port

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
       accessing 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.
