Kernel and Subsystems Technical Reference, Volume 2

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./

Implementation Specifics

This ioctl subroutine call is part of Base Operating System (BOS) Runtime.
