NAME
nng_socket_pair - create a connected pair of BSD sockets
SYNOPSIS
DESCRIPTION
The nng_socket_pair() function creates a pair of connected BSD sockets.
These sockets, which are returned in the fds array, are suitable for
use with the socket transport.
On POSIX platforms, this is a thin wrapper around the standard socketpair() function,
using the AF_UNIX family and the SOCK_STREAM socket type.
At present only POSIX platforms implementing socketpair() are supported with this function.
|
| This function may be useful for creating a shared connection between a parent process and a child process on UNIX platforms, without requiring the processes use a shared filesystem or TCP connection. |
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
ERRORS
NNG_ENOMEM
|
Insufficient memory exists. |
NNG_ENOTSUP
|
This platform does not support socket pairs. |
