AIX Version 4.3 Kernel and Subsystems Technical Reference, Volume 2
KSTDELAY (Set Typematic Delay)
Purpose
Sets typematic delay.
Syntax
#include <sys/inputdd.h>
int ioctl (FileDescriptor, KSTDELAY, Arg)
int FileDescriptor;
uint *Arg;
Description
The KSTDELAY ioctl subroutine call sets the time, specified in milliseconds, that a key must be held down before it repeats.
When keyboard diagnostics are enabled, the KSTDELAY ioctl subroutine call fails and sets the errno global variable to a value of EBUSY.
Parameters
| FileDescriptor |
Specifies the open file descriptor for the keyboard. |
| Arg |
Specifies the address of a value representing the typematic delay. The Arg parameter can be one of the following delay values:
| #define KSTDLY250 |
1 |
250ms. |
| #define KSTDLY500 |
2 |
500ms. |
| #define KSTDLY750 |
3 |
750ms. |
| #define KSTDLY1000 |
4 |
1000ms. |
Note: For the 106-keyboard, the delays are 300, 400, 500, and 600 milliseconds. All delays are +/- 20%.
