/prog/ - closures in c

Name: Anonymous 2012-01-25 2:28

thou shalt always accompany a call back with a void* argument that may be used arbitrarily by the caller:



void kind_values(struct relation* self, char* key, void(*call_back)(void* userdata, char* value), void* userdata) {

  for(char* value matching key in self) {

    call_back(userdata, value);

  }

}

and thou shalt have the satisfaction of passing a closure through the stack.
