KSCFGCLICK (Enable/Disable Keyboard Clicker)

Purpose

Configures the keyboard clicker.

Syntax

#include <sys/inputdd.h>

int ioctl (FileDescriptor, KSCFGCLICK, Arg) int FileDescriptor; uint * Arg;

Description

The KSCFGCLICK ioctl subroutine call enables and disables the keyboard clicker and sets the clicker's volume. When the keyboard clicker is enabled, the native keyboard speaker generates a sound when a key is pressed.

The KSCFGCLICK ioctl subroutine call is supported even when the workstation does not provide a keyboard clicker.

When keyboard diagnostics are enabled, the KSCFGCLICK ioctl subroutine call fails and set the errno global variable to a value of EBUSY.

Parameters

FileDescriptor

Specifies the open file descriptor for the keyboard.

Arg

Specifies an address of an integer that contains one of the following values:

#define KSCLICKOFF   0   /*Turns off clicker.*/
#define KSCLICKLOW   1   /*Sets clicker to low volume.*/
#define KSCLICKMED   2   /*Sets clicker to medium volume.*/
#define KSCLICKHI    3   /*Sets clicker to high volume.*/
