nng_sockaddr_in(5)
NAME
nng_sockaddr_in - IPv4 socket address
SYNOPSIS
DESCRIPTION
An nng_sockaddr_in is the flavor of nng_sockaddr
used to represent TCP (and sometimes UDP) addresses,
including the Internet Protocol (IP) address and port number.
This structure is used with IPv4 addresses.
A different structure, nng_sockaddr_in6, is used
for IPv6 addresses.
The following structure members are present:
sa_family-
This field will always have the value
NNG_AF_INET. sa_port-
This field holds the TCP or UDP port number, in network byte-order. A zero value here is used when no specific port number is indicated.
sa_addr-
This field holds the IP address in network-byte order.
The sa_port and sa_addr fields are in network-byte order to
facilitate their use with system APIs such as inet_ntop().
Most platforms use some form of BSD-derived network API, which uses
network-byte order in the various structures (such as sockaddr_in).
|
This field appears similar to BSD sockaddr_in, but it is
not the same, and they may not be used interchangeably.
