This function returns information about the keyboard and the keyboard driver.

Syntax

BOOL KeybdGetDeviceInfo(
  INT iIndex,
  LPVOID lpOutput 
);

Parameters

  • iIndex
    [in] Identifier of the information to retrieve. The following table shows the identifiers and their descriptions.

    Identifier

    Description

    KBDI_VKEY_TO_UNICODE_INFO_ID

    Retrieves Unicode conversion information.

    KBDI_AUTOREPEAT_INFO_ID

    Retrieves keyboard auto-repeat information.

    KBDI_AUTOREPEAT_SELECTIONS_INFO_ID

    Retrieves keyboard auto-repeat selections information.

    KBDI_KEYBOARD_STATUS_ID

    Retrieves a keyboard status identifier.
  • lpOutput
    [out] Pointer to the output buffer.

Return Value

TRUE indicates success. FALSE indicates failure. To obtain extended error information, call the GetLastError function.

Remarks

This function is part of GWES and directly calls the driver's PFN_KEYBD_DRIVER_GET_INFO function if iIndex is not KBDI_KEYBOARD_STATUS_ID. If iIndex is KBDI_KEYBOARD_STATUS_ID, this routine fills lpOutput with a DWORD combining KBDI_KEYBOARD_PRESENT, KBDI_KEYBOARD_ENABLED, KBDI_KEYBOARD_ENTER_ESC, and KBDI_KEYBOARD_ALPHA_NUM. The KBDI_KEYBOARD_ENABLED reflects the current keyboard status. The other bits are set in the registry through the HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\KEYBD\Status key.
