A structure of pointers solves nearly all the problems. And backwards
compatibility can be maintained trivially with
Another option is a key/value pair system with a sentinel tag (Apple's
OpenGL implementation does this for pixel format description). This is
a bit uglier IMO, but it generalizes better.
struct lua_callback
{
lua_callback_t cb;
int descriptor;
};
lua_callback aCallbacks[] =
{
{ myRealloc, LUA_REALLOC_CB },
{ 0, 0 }
};
lua_open( aCallbacks );
or, alternatively, ditch the sentinel and do:
lua_open( aCallbacks, sizeof( aCallbacks ) );
Point being that almost any of the solutions presented are better than
what we have right now. =)
