NAME
parport_claim - claim access to a parallel port device
SYNOPSIS
"SYNOPSIS"
int parport_claim (struct pardevice * dev);
ARGUMENTS
- dev
-
pointer to structure representing a device on the port
DESCRIPTION
This function will not block and so can be used from interrupt
context. If parport_claim succeeds in claiming access to
the port it returns zero and the port is available to use. It
may fail (returning non-zero) if the port is in use by another
driver and that driver is not willing to relinquish control of
the port.
