L_INT pEXT_CALLBACK YourFunction(hObject, pUserData)
Processes each annotation object from the L_AnnEnumerate function.
Handle of the object to be processed.
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 L_AnnEnumerate function.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
The L_AnnEnumerate function calls your callback function as it gets the handle of each annotation object.
