C++
Acad::ErrorStatus releaseExtensionDictionary();
Description
Removes the object's extension dictionary (that is, removes the object as the owner of the dictionary object) if it exists and is empty. Once removed, this function calls the dictionary's erase() method. Any reactors attached to the extension dictionary receive normal notification appropriate to an open for write, erase, close sequence.
Returns Acad::eOk if successful.
If the dictionary is not empty, then this function fails and returns Acad::eContainerNotEmpty.
Note
This function is only available in AutoCAD release R13c4a and beyond.
