       #include <sys/types.h>
       #include <sys/socket.h>

       socketpair(d, type, protocol, sv)
       int d, type, protocol;
       int sv[2];


DESCRIPTION

       The socketpair call creates an unnamed pair of connected sockets in the specified domain d, of the specified type, and using the optionally
       specified protocol.  The descriptors used in referencing the new sockets are returned in sv[0] and sv[1].  The two  sockets  are  indistin-
       guishable.

       [EPROTONOSUPPORT]   The specified protocol is not supported on this machine.

       [EOPNOSUPPORT]	   The specified protocol does not support creation of socket pairs.
