SOCKETPAIR(2)           COMMAND REFERENCE           SOCKETPAIR(2)



NAME
     socketpair - create a pair of connected sockets

SYNOPSIS
     #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 indistinguishable.

DIAGNOSTICS
     The call succeeds unless:

     [EMFILE]       Too many descriptors are in use by this
                    process.

     [EAFNOSUPPORT] The specified address family is not supported
                    on this machine.

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

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

     [EFAULT]       The address sv does not specify a valid part
                    of the process address space.

RETURN VALUE
     [0]  Socketpair was successful.

     [-1] Socketpair was unsuccessful.

CAVEATS
     This call is currently implemented only for the UTek domain.
