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.
