IDirectInputDevice8::EnumCreatedEffectObjects Method

  • Article

Enumerates all the currently created effects for this device. Effects created by IDirectInputDevice8::CreateEffect are enumerated.

Syntax

HRESULT EnumCreatedEffectObjects(
         LPDIENUMCREATEDEFFECTOBJECTSCALLBACK lpCallback,
         LPVOID pvRef,
         DWORD fl
)

Parameters

  • lpCallback
    Address of an application-defined callback function. DirectInput provides the prototype function DIEnumCreatedEffectObjectsCallback.
  • pvRef
    Reference data (context) for callback.
  • fl
    No flags are currently defined. This parameter must be 0.

Return Value

If the method succeeds, the return value is DI_OK. If the method fails, the return value can be one of the following error values: DIERR_INVALIDPARAM, DIERR_NOTINITIALIZED.

Remarks

The results are unpredictable if you create or destroy an effect while an enumeration is in progress. However, the callback function can safely release the effect passed to it.
