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.
