13) 什么是Unix domain socket
A Unixdomain socket or IPC socket (inter-process communication socket) is a datacommunications endpoint for exchanging data between processes executing withinthe same host operating system. While similar in functionality to named pipes,Unix domain socketsmay be created as connection‑mode(SOCK_STREAM or SOCK_SEQPACKET) or as connectionless (SOCK_DGRAM), while pipesare streams only. Processes using Unix domain sockets do not need to share acommon ancestry. The API for Unix domain sockets is similar to that ofanInternet socket, but it does not use an underlying network protocol forcommunication. The Unix domain socket facility is a standard component of POSIXoperating systems.Unixdomain sockets use the file system as their address name space. They arereferencedby processes as inodes in the file system. This allows two processesto open the same socket in order to communicate. However, communication occursentirely within the operating system kernel.In addition to sending data, processes may send filedescriptors acrossa Unix domain socket connection using the sendmsg() andrecvmsg() system calls.
