SYNOPSIS

14

DESCRIPTION

16       This function will not block and so can be used from interrupt context.
17       If parport_claim succeeds in claiming access to the port it returns
18       zero and the port is available to use. It may fail (returning non-zero)
19       if the port is in use by another driver and that driver is not willing
20       to relinquish control of the port.
