NAME

un.h, un - definitions for UNIX-domain sockets

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).
