int parport_claim  (struct pardevice * \fIdev\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIdev\fB\fR
pointer to structure representing a device on the port
.SH "DESCRIPTION"
.PP
This function will not block and so can be used from interrupt
context.  If \fBparport_claim\fR 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.
