io_socketpair - create a pair of sockets

       io_socketpair  creates  a  new  UNIX socket pair and writes both descriptors to d.  The socket pair works
       much like a pipe, but it is bidirectional (i.e. both descriptors are for reading and writing).

       io_socketpair returns 1 to indicate success. If something goes wrong, io_socketpair  returns  0,  setting
       errno  to  indicate the error; in this case it frees any memory that it allocated for the new socketpair,
       and it leaves d alone.
