socketpair(3c)

Standard C Library Functions                                    socketpair(3C)



NAME
       socketpair - create a pair of connected sockets

SYNOPSIS
       #include <sys/socket.h>

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

DESCRIPTION
       The  socketpair()  library  call  creates  an unnamed pair of connected
       sockets in the specified address family domain, of the specified  type,
       that  uses  the optionally specified protocol. The descriptors that are
       used in referencing the new sockets are returned in  sv[0]  and  sv[1].
       The two sockets are indistinguishable.


       Some  file descriptor flags can be specified at socket creation time to
       avoid race conditions. These options are passed  by  using  a  bitwise-
       inclusive-OR of flags with the value passed for the type parameter. See
       the socket(3C) man page for the available flags.

RETURN VALUES
       socketpair() returns −1 on failure and 0 on success.

ERRORS
       The call succeeds unless:

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


       EMFILE             Too many descriptors are in use by this process.


       ENOMEM             There was insufficient user memory for the operation
                          to complete.


       ENOSR              There were insufficient STREAMS  resources  for  the
                          operation to complete.


       EOPNOTSUPP         The  specified protocol does not support creation of
                          socket pairs.


       EPROTONOSUPPORT    The specified protocol  is  not  supported  on  this
                          machine.


       EACCES             The process does not have appropriate privileges.

HISTORY
       The socketpair() function has been present since the initial release of
       Solaris.


       Support for SOCK_* flags as part of the type  parameter  was  added  to
       Oracle Solaris in the 11.4 release.
