Keyboard Function Calls
This section reflects the Keyboard API interface of OS/2 only.
For information regarding the keyboard IOCTL interface and keyboard monitor refer to IBM Operating System/2 Version 1.2 I/O Subsystems And Device Support Volume 1.
Notes:
- Calls marked xPM are not supported by Presentation Manager, and must not be used by Presentation Manager applications. An error code is returned if any of these calls are issued.
- Calls marked xWPM are not windowable and are not supported by Presentation Manager. They can be used in OS/2 mode.
- Calls marked FAPI are present in the Family API.
| FUNCTION CALL | ICON | Description |
|---|---|---|
| KbdCharIn | FAPI xPM | This call returns a character data record from the keyboard. |
| KbdClose | xPM | This call closes the existing logical keyboard identified by the keyboard handle. |
| KbdDeRegister | xWPM | This call deregisters a keyboard subsystem previously registered within a session. |
| KbdFlushBuffer | FAPI xPM | This call clears the keystroke buffer. |
| KbdFreeFocus | xPM | This call frees the logical-to-physical keyboard bond created by KbdGetFocus |
| KbdGetCp | xPM | This call allows a process to query the code page being used to translate scan codes to ASCII characters. |
| KbdGetFocus | xPM | This call binds the logical keyboard to the physical keyboard. |
| KbdGetHWId | xPM | Returns the attached keyboard's hardware-generated Identification value. |
| KbdGetStatus | FAPI xPM | This call gets the current state of the keyboard |
| KbdOpen | xPM | This call creates a new logical keyboard. |
