Hi, I'm writing a module which requires to see request messages and also responses. So I have declared a response_function. The function looks like: static int fi_response(struct sip_msg* msg, char* str1, char* str2); and I put it into the module_exports structure like this: #ifdef STATIC_FI struct module_exports fi_exports = { #else struct module_exports exports= { #endif "fi_module", (char*[]){ "fi_request", "fi_response" }, (cmd_function[]){ fi_request, fi_response }, (int[]){ 0, 0 }, (fixup_function[]){ 0 }, 2, /* Number of exported functions*/ NULL, /* Module parameter names */ NULL, /* Module parameter types */ NULL, /* Module parameter variable pointers */ 0, /* Number of module paramers */ mod_init, fi_response, (destroy_function) 0, 0, 0 }; I'm wondering if I correctly declared the function as I'm getting a warning during compilation about incompatible pointer types (4th last line in structure where the function is declared as response function). I really only need the message as parameter. What should the parameters be? This is for the CVS version of SER. Thanks very much for your help!
