.SH NAME
parport_wait_event \- wait for an event on a parallel port
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
int parport_wait_event  (struct parport * \fIport\fB, signed long \fItimeout\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIport\fB\fR
port to wait on
.TP
\fB\fItimeout\fB\fR
time to wait (in jiffies)
.SH "DESCRIPTION"
.PP
This function waits for up to \fItimeout\fR jiffies for an
interrupt to occur on a parallel port.  If the port timeout is
set to zero, it returns immediately.
.PP
If an interrupt occurs before the timeout period elapses, this
function returns one immediately.  If it times out, it returns
a value greater than zero.  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.
