PARPORT_CLAIM_OR_BLO(9)               Parallel Port Devices               PARPORT_CLAIM_OR_BLO(9)



NAME
       parport_claim_or_block - claim access to a parallel port device

SYNOPSIS
       int parport_claim_or_block(struct pardevice * dev);

ARGUMENTS
       dev
           pointer to structure representing a device on the port

DESCRIPTION
       This behaves like parport_claim, but will block if necessary to wait for the port to be
       free. A return value of 1 indicates that it slept; 0 means that it succeeded without
       needing to sleep. A negative error code indicates failure.
