lua_pushpointer?

[RexiRexii]

if lua_topointer exists, then lua_pushpointer should also exist!

const void* lua_pushpointer(lua_State* L, TValue* idx)
{
	switch (ttype(idx))
	{
	case LUA_TNIL:
		lua_pushnil(L);
	case LUA_TBOOLEAN:
		lua_pushboolean(L, bvalue(idx));
	case LUA_TNUMBER:
		lua_pushnumber(L, nvalue(idx));
	case LUA_TSTRING:
		lua_pushstring(L, tsvalue(idx)->data);
	default:
		return NULL;
	}
}

Converted to a discussion, since this looks like a general question on learning to use Luau API.

TValue is an internal data structure so users of lua.h don't have a way of defining it.

Luau/Lua API uses numeric indices to refer to values and lua_pushvalue can be used to push a copy.
