Building a plugin system based on shared libraries.

Requirements: C++, shared libraries (windows: .dll / unix: .so) knowledge. Objective: - A plugin system for an existing source code which has many classes / functions / enums. - The shared library's functions must be used in the main app and vice versa. - The main app's functions must be used in the shared library. - There has to be a folder (windows plugins/*.dll Unix plugins/*.so). the plugin system must load these libraries and share the main app's functions and load their functions automatically. example main app class: CTextParser { public: bool Load(const char * c_szFileName); const char * GetFileName(); }; example of a shared library function: CTextParser * parser; parser->Load("[login to view URL]"); Those functions and other functions must be used inside the shared libraries.
