Speaking of which, and since explicit use of blocks are the way to go,
I was wondering how to use those in C callbacks that are used by Lua code;
if I register:
void hook_lua_getstuff()
{
lua_beginblock();
lua_pushnumber(stuff);
lua_endblock();
}
a question comes to mind:
- do I use blocks (the code in the function can get large and use a whole
pile of Lua calls)
- if I use them, since lua_endblock empties the stack, should I put it
before the lua_pushnumber call (or any call that pushes, but could
call Lua to do so) ?
What is the Right Thing to do in this case ?
