PARPORT_WAIT_EVENT(9) Parallel Port Devices PARPORT_WAIT_EVENT(9)
NAME
parport_wait_event - wait for an event on a parallel port
SYNOPSIS
int parport_wait_event(struct parport * port, signed long timeout);
ARGUMENTS
port
port to wait on
timeout
time to wait (in jiffies)
DESCRIPTION
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.
