I am writing `D2` bindings for Lua. This is in one of the Lua header files.
typedef int (*lua_CFunction) (lua_State *L);
I assume the equivalent `D2` statement would be:
extern(C) alias int function( lua_State* L ) lua_CFunction;
Lua also provides an api function:
void lua_pushcfunction( lua_State* L, string name, lua_CFunction func );
If I want to push a `D2` function does it have to be extern(C) or can I just use the function?
int dfunc( lua_State* L )
extern(C) int cfunc( lua_State* L )
lua_State* L = lua_newstate();
lua_pushcfunction(L, "cfunc", &cfunc); //This will definitely work.
lua_pushcfunction(L, "dfunc", &dfunc); //Will this work?
If I can only use `cfunc`, why? I don't need to do anything like that in `C++`. I can just pass the address of a `C++` function to `C` and everything just works. There are some bindings that currently exsist, not sure how good they are: code.google.com/p/dlua
