ANNENUMCALLBACK Function
#include "l_bitmap.h"
L_INT pEXT_CALLBACK YourFunction(hObject, pUserData)
HANNOBJECT hObject; |
/* object handle */ |
L_VOID *pUserData; |
/* pointer to additional data */ |
Processes each annotation object from the L_AnnEnumerate function.
Parameter |
Description |
hObject |
Handle of the object to be processed. |
pUserData |
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. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The L_AnnEnumerate function calls your callback function as it gets the handle of each annotation object.
