PARPORT_CLAIM(9) Parallel Port Devices PARPORT_CLAIM(9) NAME parport_claim - claim access to a parallel port device 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. COPYRIGHT Kernel Hackers Manual 2.6.
