This call allows a process to query the code page being used to translate scan codes to ASCII characters.

Syntax

KbdGetCp (Reserved, CodePageID, KbdHandle)

Parameters

Reserved (ULONG) - input: Reserved and must be set to zero.
CodePageID (PUSHORT) - output: Address of the code page ID located in the application's data area. The keyboard support copies the current code page ID for a specified keyboard handle into this word. The code page ID is equivalent to one of the code page IDs specified in the CONFIG.SYS CODEPAGE = statement or 0000.
KbdHandle (HKBD) - input: Default keyboard or the logical keyboard.

Return Code

rc (USHORT) - return

Return code descriptions are:

0 NO_ERROR
373 ERROR_KBD_PARAMETER
439 ERROR_KBD_INVALID_HANDLE
445 ERROR_KBD_FOCUS_REQUIRED
447 ERROR_KBD_KEYBOARD_BUSY
464 ERROR_KBD_DETACHED
504 ERROR_KBD_EXTENDED_SG

Remarks

The CodePageID is the currently active keyboard code page. A value of 0 indicates the code page translation table in use is the ROM code page translation table provided by the hardware.
