nn_socket(3compat)

NAME

nn_socket - create socket (compatible API)

#include <nanomsg/nn.h>

int nn_socket(int af, int proto);

The nn_socket() function creates socket using the address family af and protocol proto and returns it.

Note	This function is provided for API compatibility with legacy libnanomsg. Consider using the relevant modern API instead.

Important

Mixing the compatibility API and the modern API is not supported on a given socket.

Note	Some protocols, transports, and features are only available in the modern API.

The address family af can be one of two values:

`AF_SP`	Normal socket.
`AF_SP_RAW`	“Raw mode” socket.

The protocol indicates the protocol to be used when creating the socket. The following protocols are defined:

This function returns a valid socket number on success, and -1 on failure.

`ENOMEM`	Insufficient memory is available.
`ENOTSUP`	The protocol is not supported.
`ETERM`	The library is shutting down.
