IDebugEventCallbacks::GetInterestMask

The GetInterestMask callback method is called to determine which events the IDebugEventCallbacks object is interested in. The engine calls GetInterestMask when the object is registered with a client by using SetEventCallbacks.

HRESULT
  IDebugEventCallbacks::GetInterestMask(
    OUT PULONG  Mask
    );

HRESULT
  IDebugEventCallbacksWide::GetInterestMask(
    OUT PULONG  Mask
    );

#ifdef UNICODE
#define IDebugEventCallbacksT IDebugEventCallbacksWide
#else
#define IDebugEventCallbacksT IDebugEventCallbacks
#endif

Parameters

Mask

Receives a bitmask that indicates which events the object is interested in. The engine will call only those methods that correspond to the bit flags set by GetInterestMask. For a description of the bit flags and their corresponding methods, see DEBUG_EVENT_XXX.

Return Value

The return value S_OK indicates the method was successful. All other return values indicate an error occurred, in which case the SetEventCallbacks call will fail and the callback object will not be used nor will it receive events.

Comments
