* You cleanup the stack, thus removing the stack entry with the

In your opinion, this code is correct?
if (lua_getmetatable(L, 2)) {
lua_getfield(L, -1, "namefield");
if (lua_isuserdata(L, -1)) {
MyCtype func = (MyCtype) lua_touserdata(L, -1);
int n = 1;
if (func != NULL) {
void * child = lua_touserdata(L, 2);
control = (*func)(child);
++n; /* pop child */
}
lua_pop(L, n); /* pop child and MyCType */
}
}
