parport_wait_event9
Wait for an event on a parallel port
Usage
int parport_wait_event(struct parport * port, signed long timeout);
Arguments
port
port to wait on
timeout
time to wait (in jiffies)
Overview
This function waits for up to timeout jiffies for an interrupt to occur on a parallel port. If the port timeout is set to zero, it returns immediately.
If an interrupt occurs before the timeout period elapses, this function returns zero immediately. If it times out, it returns one. An error code less than zero indicates an error (most likely a pending signal), and the calling code should finish what it's doing as soon as it can.
