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

KbdGetCp (Reserved, CodePageID, KbdHandle)

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. 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.
