Purpose

Disables an input device for event queuing

Libraries

Graphics Library

C (libgl.a)

FORTRAN (libfgl.a)

C Syntax

void unqdevice(Device dev)

FORTRAN Syntax

SUBROUTINE UNQDEV(dev)
INTEGER*4 dev

Description

The unqdevice subroutine removes the specified device from the list of devices whose changes are recorded in the event queue. If a device has recorded events that have not been read, they remain in the queue.

Use the qreset subroutine to flush the event queue.

Note: This subroutine cannot be used to add to a display list.

Parameter

dev

Specifies an identifier for the device to be disabled.

Example

The example C language program prompt.c uses the unqdevice subroutine to disable input from the keyboard.
