inet_ntop - Parse network address structures
af, const void *src,
char *dst, size_t cnt);
This function converts the network address structure
src in the af address family into a character
string, which is copied to a character buffer dst,
which is cnt bytes long.
inet_ntop(3) extends the __inet_ntoa__(3)? function
to support multiple address families, inet_ntoa(3) is
now considered to be deprecated in favor of
inet_ntop(3). The following address families are
src points to a struct in_addr (network byte
order format) which is converted to an IPv4 network address
in the dotted-quad format,
must be at least INET_ADDRSTRLEN bytes
src points to a struct in6_addr (network byte
order format) which is converted to a representation of this
address in the most appropriate IPv6 network address format
for this address. The buffer dst must be at least
INET6_ADDRSTRLEN bytes long.
inet_ntop returns a non-null pointer to dst.
NULL is returned if there was an error, with errno
set to EAFNOSUPPORT if af was not set to a
valid address family, or to ENOSPC if the converted
address string would exceed the size of dst given by
the cnt argument.
AF_INET6 converts IPv6-mapped IPv4 addresses into an
