Synopsis

#include <sys/un.h>

Description

The <sys/un.h> header defines the sockaddr_un structure that includes the following members:

sa_family_t  sun_family   /* address family */
char         sun_path[]   /* socket pathname */

The sockaddr_un structure is used to store addresses for UNIX domain sockets. Values of this type must be cast to struct sockaddr for use with the socket interfaces.

The <sys/un.h> header defines the type sa_family_t as described in socket.h(3HEAD).
