Function name macro in C++

Question

I have a c++ macro that looks like this

#define lua_tpushstring(L,n,f) \
            (lua_pushstring(L, n), lua_pushstring(L, f))

I want to modify it so it works like this

#define lua_tpush(TYPE,L,n,f) \
            (lua_pushstring(L, n), lua_pushTYPE(L, f))

lua_tpush(boolean, L, "a", true);
lua_tpush(string, L, "a", "");

What is the simple change?

Answer 1

Token concatenation:

#define lua_tpush(TYPE,L,n,f)  (lua_pushstring(L, n), lua_push##TYPE(L, f))
