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