lua_resume's first argument is *the thread itself*. So you need 
something like this:

{
  lua_State *L1;
  lua_getglobal(L, "my_coroutine");
  L1 = lua_tothread(L, -1); /* get the thread */
  /* make sure L1 is not NULL */
  status = lua_resume(L1, 0); /* resume the thread */
  /* make sure status is 0 */
  lua_pop(L, 1);
}

if you need to pass arguments or receive results, see lua_xmove()
