Unix domain socket

POSIX local inter - process communication sockets ( Unix domain socket or IPC socket ) are endpoints of bidirectional communication links with the local inter-process communication (IPC) in Unix operating systems. Communication on these sockets is standardized in POSIX - standard method for inter-process communication on Unix -like systems. According to the Unix philosophy ( " everything is a file " ) are sockets via an inode in the file system can be addressed and can be addressed using the same commands as ordinary files. To communicate, open two processes the same socket. The data flow as a stream of bytes from buffer to buffer memory in kernel memory. Addition data and file handle can be transmitted on the socket connections with the system calls, SendMsg () and recvmsg ().
