A company has asked me to find out if they can buy a library (C++) (from Autodesk) which will read and write DWG files. They do not make CAD programs, but their clients use AutoCAD.
If their clients use AutoCAD then they don't need RealDWG licensing. To interact with AutoCAD they can create programs inside it or around it using autolisp/visual lisp, dotNet (c++, C#, F# and visual basic), Python and JavaScript. Reading writing to dwg/dxf are carried out by AutoCAD . If they want to use RealDWG in an application that is not related to AutoCAD , but they i/o functionality for this data format, then they need license agreement. Current yearly cost of license for up to 10 000 users is 8000 US$/7500 € as stated here.
