search for: struct_name_vfunc

...in mentioned above. The only clue I have got yet is the definition in module-context.h: union STRUCT_NAME_module_context { struct STRUCT_NAME_module_register *reg; // it's allowed to have some structure here so it won't waste space. // for example: struct STRUCT_NAME_vfuncs super; }; However, I still cannot make any sense of it (yet). Could you please help me in filling the gap and understanding, what has to be changed? Thanks a lot in advance for an awesome piece of software and any input on this topic, Lukas
