Creating the DLL |
![]() ![]() |
To be recognized as an Extension library, the DLL must export the 2 functions
mb_ext_load mb_ext_unload
If you use MS Visual Studio make sure there is no function name decorations so use extern "C" when exporting the names. Use mb_ext_load to register the functions when the DLL is loaded and then remove the functions when it is unloaded in mb_ext_unload. The 3rd parameter of mb_register_func is the addess of a callback function that will be called when the function is being invoked. This function will parse any parameters and implement the function.
Example:
///////////////////////////////////////////////////////////////////////////// // Function Callback int _my_function_callback( mb_interpreter_t* s, void** l ) { // Parse and process....
return MB_FUNC_OK; }
///////////////////////////////////////////////////////////////////////////// // Load and Register Functions extern "C" __declspec(dllexport) int mb_ext_load( mb_interpreter_t* s ) { mb_register_func( s, "MYFUNCTION", _my_function_callback ) }
///////////////////////////////////////////////////////////////////////////// // Remove regsitered functions extern "C" __declspec(dllexport) int mb_ext_unload( mb_interpreter_t* s ) { mb_remove_func( s, "MYFUNCTION" ); }
