un.h, un - definitions for UNIX-domain sockets
#include <sys/un.h>
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).
