Lua persistence library?

[Chuck Messenger <cmessenger@...>]

Is there a Lua persistence library?  What I'd like is to have:

int lua_save(lua_State *L, char *buf, int len);
lua_State *lua_restore(char *buf, int len);

lua_save() would write the existing VM state to buf (which
is len bytes long).  It would return the number of bytes
used.

lua_restore() would regenerate the Lua VM state from the
same buffer.

It would be cross-platform -- that is, you could save the
state on, say, a Mac, and restore it on a PC.

Is there anything like this out there?
