Callback for tracking and aborting long-running operations.
Reserved for future use.
A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the
pUserData parameter of the calling function.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
|SUCCESS||The function was successful. The default processing for this marker can be performed.|
|ERROR_USER_ABORT||Abort the caller filter operation.|
|< 1||An error occurred. Refer to Return Codes.|
