SYNOPSIS
#include <nng/nng.h>
enum sockaddr_family {
NNG_AF_ZT = 5,
};
typedef struct {
uint16_t sa_family;
uint64_t sa_nwid;
uint64_t sa_nodeid;
uint32_t sa_port;
} nng_sockaddr_zt;DESCRIPTION
An nng_sockaddr_zt is the flavor of nng_sockaddr
used to represent ZeroTier addresses, including the
port number used by the
zt transport.
| The ZeroTier transport, and the details of this structure, are still considered experimental, and subject to change. |
The following structure members are present:
sa_family-
This field will always have the value
NNG_AF_ZT. sa_nwid-
This field holds the ZeroTier network number (or ID). This value is in native byte order.
sa_nodeid-
This field holds the ZeroTier node ID. This value is in native byte order, and only the lower 40 bits are significant. (ZeroTier node numbers are 40 bits long.) A zero value here is used for a wild-card to indicate that the caller’s own node number be used.
sa_port-
This field holds the “port number” used by the zt transport to distinguish different sockets. This value in native byte order. A zero value here indicates that a port number should be chosen randomly from the ephemeral ports. Only the lower 24 bits of the port number are used.
| ZeroTier port numbers are in native byte order, and are larger than TCP/IP port numbers. They are also not part of the ZeroTier protocol itself, but defined by the Scalability Protocols binding for them. |
