NAME

       inet_ntop - Parse network address structures

SYNOPSIS

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <arpa/inet.h>

       const char *inet_ntop(int af, const void *src,
			     char *dst, size_t cnt);

DESCRIPTION

       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 supported:

       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 dst 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 dst must be at least INET6_ADDRSTRLEN bytes long.

RETURN VALUE

       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.

BUGS

       AF_INET6 converts IPv6-mapped IPv4 addresses into an IPv6 format.
