IEEE1284_CLAIM(3)		   Functions		     IEEE1284_CLAIM(3)

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.
