I've got a C program that Lua could return a function to and I'd

save that function to call later when an event occurs. What do I
need to
save so I can call the function? How do I call the function?
Something like
lua_getfield(aLua, -1, "function");
if (!lua_isnil(aLua, -1))
{
lua_pushvalue(aLua, -1); // Push it because luaL_ref pops
int fnRef = luaL_ref(aLua, LUA_REGISTRYINDEX);
and
lua_rawgeti(lua, LUA_REGISTRYINDEX, m_Ref);
int error = lua_pcall(lua, 0, 0, - 2);
