function foo(a)
-- ...
return a, b
end
I got this function which returns a and b. Is it possible to register a C function using lua_register() that returns multiple values the same way? Or should I resort to push a table to the stack instead?

Yes,

leave the arguments that you want to return on the stack and let the C function return the numbers of arguments you want to return to lua


// psudeo
int cfunction(lua_State * state)
{
push(arg1)
push(arg2)

return 2;
}
