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
