If a fucntion has a char* parameter like this: void print(const char* pMsg); And I registed this function with description string: void print(const string & in) Then, the parameter cannot be passed correctly. How do you resolve this problem?

In this case you'll have to write a wrapper.

void print(const char *pMsg);void wrapper_for_print(const string &msg){  print(msg.c_str();}r = engine->RegisterGlobalFunction("void print(const string ∈)", asFUNCTION(wrapper_for_print), asCALL_CDECL); assert( r >= 0);
