Description: 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.
