The function based on this prototype initializes the virtual-key code state and driver-specific state.

Syntax 

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 Value

None.

Remarks

After calling the PFN_KEYBD_DRIVER_GET_INFOfunction and allocating its required memory, the input system calls this function to enable the driver to initialize the memory.

The pKeybdDriverToUnicodeStateparameter is a pointer to a block of memory of at least cbToUnicodeStatebytes, as reported by the PFN_KEYBD_DRIVER_GET_INFOfunction in the KBDI_VKEY_TO_UNICODE_INFOstructure. If cbToUnicodeStateis 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_STATESfunction and multiple threads can call it.

Requirements

Header keybddr.h
Library layoutmanager.lib
Windows Embedded CE Windows CE 1.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
