Structure Description:

    This structure defines a Unix socket address.

Members:

    sun_family - Stores the address family, AF_UNIX in this case.

    sun_path - Stores the null-terminated path string. The size of the socket
        address passed around should include the length of this string plus the
        null terminator.
