The ANNHITTESTINFO structure provides hit test information for the L_AnnHitTest function.



Size of this structure. Use sizeof(HITTESTINFO).


This is the zero-based index of the handle. This field is valid only if puResult of L_AnnHitTest is updated with either ANNHIT_HANDLE or ANNHIT_USER_HANDLE. The default handles and the user handles are maintained internally as separate arrays of handles. This means that there is both a default handle "0" and a user handle "0". This index can be used with other annotation handle functions.


The unique ID associated with the user handle. The ID can be set with the L_AnnAddUserHandle, L_AnnChangeUserHandle, L_AnnEnumerateHandles functions.


Reserved for future use. Set this field to zero.


For an example showing the use of this structure, refer to L_AnnHitTest.
