The RegisterRawInputDevices function registers the devices that supply the raw input data.
Syntax
BOOL RegisterRawInputDevices(
PCRAWINPUTDEVICE pRawInputDevices,
UINT uiNumDevices,
UINT cbSize
);
Parameters
- pRawInputDevices
-
[in] Pointer to an array of RAWINPUTDEVICE structures that represent the devices that supply the raw input.
- uiNumDevices
-
[in] Number of RAWINPUTDEVICE structures pointed to by pRawInputDevices.
- cbSize
-
[in] Size, in bytes, of a RAWINPUTDEVICE structure.
Return Value
TRUE if the function succeeds; otherwise, FALSE. If the function fails, call GetLastError for more information.
Remarks
To receive WM_INPUT messages, an application must first register the raw input devices using RegisterRawInputDevices. By default, an application does not receive raw input.
If a RAWINPUTDEVICE structure has the RIDEV_REMOVE flag set and the hwndTarget parameter is not set to NULL, then parameter validation will fail.
