+1、目录结构：
+├── Makefile makefile
+├── msgrcv.c 消息队列接收测试程序
+├── msgsnd.c 消息队列发送测试程序
+└── readme 本文件
+
+
+2、说明
+2.1、针对msgget/msgrcv/msgsnd接口
+2.2、msgget依靠key创建消息队列，约定：0x0~0xFFFEFFFF为本核消息区间，0xFFFF0000~0xFFFFFFFF为车载双核跨核消息（针对非跨核工程，依然是本核消息）。
+
+3、使用说明
+3.0、只针对车载版本的测试程序，测试程序名为 msgsnd/msgrcv。
+3.1、AP侧跨核发送测试：msgsnd key （key为int型整数，这里选取0xFFFF0000~0xFFFFFFFF范围，例如-200）
+ CAP侧运行msgrcv key，使用相同的key进行接收，会获取AP侧发送的消息内容并进行打印。
+3.2、AP侧跨核接收测试：msgrcv key （这里同样选择-200），CAP核运行msgsnd -200进行发送。
+3.3、AP侧本核发送测试：key取值范围0x0~0xFFFEFFFF即为本核消息。
+3.4、AP侧本核接收测试：同上。
+
+4、示例：
+4.1、跨核AP->CAP
+ AP：
+ # msgsnd -200
+ Message id: 10
+ Write Message : helloworld
+ Sent message ret is 0 message is : helloworld
+ CAP：
+
+ # msgrcv -200
+ Message id: 10
+ Received Message len is 104, message is : helloworld
+
+4.2、跨核CAP->AP
+ CAP:
+ # msgsnd -200
+ Message id: 11
+ Write Message : nihaoshijie
+ Sent message ret is 0 message is : nihaoshijie
+ AP:
+ # msgrcv -200
+ Message id: 11
+ Received Message len is 104, message is : nihaoshijie
+
+4.3、本核消息队列
+ AP：
+ # msgsnd 100
+ Message id: 12
+ Write Message : huanying
+ Sent message ret is 0 message is : huanying
+ AP：
+ # msgrcv 100
+ Message id: 12
+ Received Message len is 104, message is : huanying
