NAME

6       parport_wait_event - wait for an event on a parallel port
7

SYNOPSIS

9       int parport_wait_event(struct parport * port, signed long timeout);
10

ARGUMENTS

12       port
13           port to wait on
14
15       timeout
16           time to wait (in jiffies)
17

DESCRIPTION

19       This function waits for up to timeout jiffies for an interrupt to occur
20       on a parallel port. If the port timeout is set to zero, it returns
21       immediately.
22
23       If an interrupt occurs before the timeout period elapses, this function
24       returns zero immediately. If it times out, it returns one. An error
25       code less than zero indicates an error (most likely a pending signal),
26       and the calling code should finish what it's doing as soon as it can.
