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.

    Note

    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.
