The function based on this prototype initializes the virtual-key code state and driver-specific state.
typedef BOOL (*PFN_KEYBD_DRIVER_INIT_STATES)( INT iKeybdId, KEY_STATE KeyState, void *pKeybdDriverState);
Parameters
- iKeybdId
[in] Identifier of the keyboard to initialize key state data. - KeyState
[out] Key state to initialize. - pKeybdDriverState
[in] Keyboard-specific state to initialize.
Return Values
None.
Remarks
After calling the PFN_KEYBD_DRIVER_GET_INFO function and allocating its required memory, the input system calls this function to enable the driver to initialize the memory.
The pKeybdDriverToUnicodeState parameter is a pointer to a block of memory of at least cbToUnicodeState bytes, as reported by the PFN_KEYBD_DRIVER_GET_INFO function in the KBDI_VKEY_TO_UNICODE_INFO structure. If cbToUnicodeState is reported as zero, this parameter can be NULL.
This function must be re-entrant because the input system exposes it through the PFN_KEYBD_DRIVER_INIT_STATES function and multiple threads can call it.
Requirements
OS Versions: Windows CE 1.0 and later.
Header: Keybddr.h.
Link Library: LayoutManager.lib.
