virtual L_INT LAnnEncrypt::GetUserHandles(pAnnHandle, pCount)
pANNHANDLE pAnnHandle; |
array of ANNHANDLE structures that define user handles |
L_UINT *pCount; |
pointer to an unsigned integer used to return the total count of user handles |
Gets information about all existing user-defined annotation handles.
Parameter |
Description |
pAnnHandle |
Array of ANNHANDLE structures to be updated with the user-defined handles. |
pCount |
Pointer to an unsigned integer used to return the total number of user handles. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Call with pAnnHandle == NULL to get the total number of user handles. Then allocate memory for an array of ANNHANDLE structures and call this function again.
Gets an array of user-defined handles associated with the annotation object.
