C++
virtual Acad::ErrorStatus writeXDataStart();
Description
If the filer is filing to AutoLISP or ADSRX, then this function writes out the AcDb::DxfCode::kDxfXDataStart (value of -3) to indicate the start of xdata. If the filer is filing to a DXF file, then this function does nothing.
Note
This function is intended for internal use. The filing of xdata and the AcDb::kDxfXDataStart code are automatically taken care of by the ObjectARX filing mechanism. The only time this method might be used by an ObjectARX application would be during a custom filing operation.
