ANNENUMCALLBACK Function

#include "l_bitmap.h"

L_INT pEXT_CALLBACK YourFunction(hObject, pUserData)

HANNOBJECT hObject;

/* object handle */

L_VOID L_FAR * 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.

Example
