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.
