Description: A<========>B<=========>C<=====>D<======>E
A与B进程之间通过TCP的socket传递 主要掌握socket的流程：
A服务器端：
socket -->bind---->listen---->accept send read
B客户端：
socket-->connect->read send
不懂的可以man一下 man socket
B与C使用共享内存来交互
步骤是：shmget->shmat->直接读写--->shmdt shmctl(删除)
可以man
C与D之间使用消息传递进行
msgget-->msgrcv->msgsnd (注意这里的返回值判断发送正确与否 不是发送的字节数)
D使用fork（） 创建了一个进程 E
D跟E之间使用无名管道进行交互
E程序中可以使用有名管道 进行通讯。(A<========>B<=========>C<=====>D<======>E
Between the A and the B processes, the process of master socket is passed through the socket of the TCP:
A server side:
Socket -->bind---->listen---->accept send read
B client:
Socket-->connect->read send
Do not understand the ability to man man socket
B and C interact with shared memory
The step is: shmget->shmat-> read and write --->shmdt shmctl directly (delete)
Can man
Message passing between C and D
Msgget-->msgrcv->msgsnd (note that the return value here determines whether to send correctly or not the number of bytes sent)
D uses fork () to create a process E
Interaction between D and E using anonymous pipes
E programs can communicate with famous pipes.)
