Use member function for pthread and detach in C++

gistfile1.cpp

int T::method() {
  return 0;
}

// static member function
void *T::threadStart(void *obj) {
  int ret;
  T *me = reinterpret_cast<T *>(obj);
  ret = me->method();
  return (void *)ret;
}

int T::run(void) {
  pthread_t t;
  int ret;

  ret = pthread_create(&t, NULL, T::threadStart, this);
  if (ret) {
    printf("Cannot create thread\n");
    return ret;
  }

  ret = pthread_detach(t);
  if (ret) {
    printf("Cannot detach thread\n");
    return ret;
  }

  return ret;
}
