How to monitor that the filesystem pathname is renamed in C or inotify?

int main(){
  int length, i = 0, fd, wd;
  char buffer[EVENT_BUF_LEN];

  fd = inotify_init();
  if (fd < 0){
      perror( "inotify_init" );
  }
  wd = inotify_add_watch(fd, pathname1, IN_MODIFY);
  length = read( fd, buffer, EVENT_BUF_LEN); 
  if(length < 0){
      perror("read");
  }  

  while(i < length){     
    struct inotify_event *event = ( struct inotify_event *)&buffer[i];
      if(event->len){
          if(event->mask & IN_MODIFY){
              if(event->mask & IN_ISDIR){
                if(event->wd == wd){
                  // if directory name changed. I don't know what condition to put
                  printf("The directory name '%s' is changed with %s\n", event->name);
                }
              }
              else{
                if(event->wd == wd){
                  // if file name changed. I don't know what condition to put
                  printf("The file name '%s' is changed with %s\n", event->name);
                }
              }
          }
      }
      i += EVENT_SIZE + event->len;
  }
    inotify_rm_watch(fd, wd);
  close(fd);
}

What I have tried:

In this code, I am monitoring a file and a directory. But I have a problem that I want to solve and that is, what condition to put that which file or a directory is renamed? Although the IN_MODIFY only works with the file when that file text is modified. But I want to monitor that if the file or directory is renamed
Is it possible with inotify or with C?
