inet_ntop - Parse network address structures
const char *p=inet_ntop(int 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 currently
AF_INET src points to a struct in_addr (network byte order
format) which is converted to an IPv4 network address in
the dotted-quad format, "ddd.ddd.ddd.ddd". The buffer
buf must be at least INET_ADDRSTRLEN bytes long.
AF_INET6 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 buf must be at least
INET6_ADDRSTRLEN bytes long.
inet_ntop returns a non-null pointer to buf. 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 buf, given by the cnt argument.
AF_INET6 converts IPv6-mapped IPv4 addresses into an IPv6 format.
