[Freeswitch-users] How to create a C++ application (project), that can code FS C code function?

Hi there, I am new to FreeSwitch and I would like to implement a C++ application / mod that would do some analysis of RTP packets. I would like to ask what mod I should use as a template to create my C++ project so that I can access the core FreeSwitch APIs / functions, since they are in C language? I know under Endpoints, there are 2 MODs that are using C++ code (mod_h323 and mod_opal), but I don't know if I should implement the same way if I am creating an "application" instead of "endpoints". Please kindly let me know if there is any special / required function that I need to implemented in C++ code. Thanks in advance. Frankie
