SYNOPSIS
#include <nanomsg/nn.h>
int nn_device(int sock1, int sock2);DESCRIPTION
The nn_device() function is used to create a forwarder, where messages
received on one of the two sockets sock1 and sock2 are forwarded to
the other.
| This function is provided for API compatibility with legacy libnanomsg. Consider using the relevant modern API instead. |
The two sockets must be compatible, and must be raw mode sockets. More detail about devices and how they can be used is available in the new style nng_device() documentation.
RETURN VALUES
This function blocks forever, and will return -1 only when one of the sockets is closed or an error occurs.
ERRORS
EBADF-
One of the two sockets is invalid or not open, or has
EINVAL-
The sockets are not compatible with each other, or not both raw.
ENOMEM-
Insufficient memory is available.
