Sorry, just realised my previous reply was horrible confused and wrong.
I don't knowing anything about Lua 3.1 (it was 3.2 when I first
started using Lua) but it's not the sort of thing that became possible
until coroutines (Lua 5.0).
No problem.
So, anyone have some thoughts? Right now I think the "easiest" (heh!)
way of doing this is to instrument the Lua function's bytecode at
runtime (from the C function), and insert a "RETCODE" or equivalent in
the appropriate spot, although I'm not espcially happy about this.
Any suggestions?
