If I understood correctly, here's what the manual says of lua_yield():

 This function should only be called as the return _expression_
 of a C function, as follows:

   return lua_yield (L, nresults);

You can't insert a printf after the yield. If you have to, return normally and do a coroutine.yield on the Lua side (I used both methods and they work fine).

I thought the coro patch enables writing normal C methods and yield from/resume to them. 

In particular you can now: 

 

• Yield from C functions and resume back to them.

At least that's what is said on http://luajit.org/coco.html.

And if that's not possible, how else can i handle it? I mean I need to be able to pass stuff to C when yielding and pass stuff back to Lua when resuming, in some way.
