互斥体不同步C++

我有2个过程。第一个向另一个发送一些数据,同步每个移动。 它实际发送数据如下:

 Process : A sends 1
 Process : B receives 1
 Process : A sends 2
 Process : B receives 2

问题是,当我运行进程A时,它从一开始就发送所有数据,我看到如下情况:

 Process : A sends 1
 Process : A sends 2
 Process : A sends 3
 Process : B receives 3

我做了如下工作:

  Process A
   HANDLE mutex;    
    mutex = CreateMutex(NULL, FALSE, TEXT("mutex1"));
    if (mutex == INVALID_HANDLE_VALUE) {
        _tprintf(TEXT("Create mutex error !.\n"), GetLastError());
        return 1;
    }
   for (int i = 0; i < sender_length;i++) {
       WaitForSingleObject(mutex,INFINITE);
       sendToB(data);
       ReleaseMutex(mutex);
       }

     CloseHandle(mutex);

B过程如下所示:

 Process B:

  HANDLE mutex;

    mutex = OpenMutex(SYNCHRONIZE, FALSE, TEXT("mutex1"));

    if (mutex == INVALID_HANDLE_VALUE) {
        _tprintf(TEXT("Mutex error ! \n"), GetLastError());
        return 1;
      }
     for (int i = 0; i < sender_length;i++) {
           WaitForSingleObject(mutex,INFINITE);
           receiveFromA(data);
           ReleaseMutex(mutex);
           }

         CloseHandle(mutex);
