HRESULT AXAUTOEXP AcAxGetXData( const AcDbObjectId& objId, BSTR bstrName, VARIANT* type, VARIANT* data );
File
axboiler.h
Description
Gets the xdata on the object identified by the objId.
Note
Each element in type corresponds to an element in data.
Returns HRESULT. The macros SUCCEEDED() and FAILED() can be used to determine whether the function succeeded. The return value should be forwarded to the COM client; nothing else needs to be done. The function cleans up after itself in case of an error and also sets up the Error Info object that can be queried from the COM client to get specific information about what caused any given failure.
