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.
