When introducing the process, you should pay more attention to some details. First, bindService also uses ContextWrapper. bindService to bindService of ContextImpl, and then bindServiceCommon.

Ladies and gentlemen, crossing, the last time we were talking about the socket communication example, let's go on to this example. Gossip Hugh, words return to the positive. Let's talk C chestnuts together!Crossing, we described the system calls used during socket communication in the previous section, which are generic and can be used in any type of socket communication. Today, we will introduce some system calls that are specifically designed to send and receive data through sockets. The funct

client sends a SYN, SEQ, request to establish a connection like the server, at which time the state is in syn_sent4.
