nng_pair_open(3)

NAME

nng_pair_open - create pair socket

SYNOPSIS

Version 0

#include <nng/protocol/pair0/pair.h>

int nng_pair0_open(nng_socket *s);

int nng_pair0_open_raw(nng_socket *s);

Version 1

#include <nng/protocol/pair1/pair.h>

int nng_pair1_open(nng_socket *s);

int nng_pair1_open_raw(nng_socket *s);

int nng_pair1_open_poly(nng_socktet *s);

DESCRIPTION

The nng_pair0_open() and nng_pair1_open() functions create a pair version 0 or version 1 socket and return it at the location pointed to by s.

The nng_pair0_open_raw() and nng_pair1_open_raw() functions create a pair version 0 or version 1 socket in raw mode and return it at the location pointed to by s.

The nng_pair1_open_poly() function opens a pair version 1 socket in polyamorous mode.

Polyamorous mode is deprecated and should not be used in new applications. The nng_pair1_open_poly() function will likely be removed in a future release.

RETURN VALUES

These functions returns 0 on success, and non-zero otherwise.

ERRORS

`NNG_ENOMEM`	Insufficient memory is available.
`NNG_ENOTSUP`	The protocol is not supported.
