DIEnumDevicesCallback Function

Application-defined callback function that receives Microsoft?DirectInput?devices as a result of a call to the IDirectInput8::EnumDevices method.

Syntax

BOOL CALLBACK DIEnumDevicesCallback(      

    LPCDIDEVICEINSTANCE lpddi,
    LPVOID pvRef
);

Parameters

lpddi

Address of a DIDEVICEINSTANCE structure that describes the device instance.

pvRef

The application-defined value passed to IDirectInput8::EnumDevices or IDirectInput8::EnumDevicesBySemantics as the pvRef parameter.

Return Value

Returns DIENUM_CONTINUE to continue the enumeration or DIENUM_STOP to stop the enumeration.

Remarks

If a single hardware device can function as more than one DirectInput device type, it is enumerated as each device type that it supports. For example, a keyboard with a built-in mouse is enumerated twice: once as a keyboard and once as a mouse. The product globally unique identifier (GUID) is the same for each device, however.
