what is sockaddr_un

I searched this term on net sockaddr_un I am trying my hands from beejs network programming guide.http://beej.us/guide/bgnet/output/ht...age/bgnet.html
In this guide it is no where mentioned about struct sockaddr_un
where as I see in linux/un.h
following struct

Code:



struct sockaddr_un {

        sa_family_t sun_family; /* AF_UNIX */

        char sun_path[UNIX_PATH_MAX];  /* pathname */

};

What is the above used for?

Sockets can use many different transports, not just TCP/IP ("AF_INET").

In this case, "sockaddr_un" holds an address for "Unix sockets" ("AF_UNIX"):
