       inet_ntop - convert IPv4 and IPv6 addresses from binary to text form

       #include <arpa/inet.h>

       const char *inet_ntop(int af, const void *src,
			     char *dst, socklen_t size);

       This  function  converts	 the  network  address structure src in the af
       address family into a character string.	The resulting string is copied
       to the buffer pointed to by dst, which must be a non-null pointer.  The
       caller specifies the number of bytes available in this  buffer  in  the
       argument size.

       inet_ntop()  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().	 The  following address families are currently

	      src points to a struct in_addr (in network byte order) which  is
	      converted	 to an IPv4 network address in the dotted-decimal for‐
	      mat,  "ddd.ddd.ddd.ddd".	 The  buffer  dst  must	 be  at	 least
	      INET_ADDRSTRLEN bytes long.

	      src points to a struct in6_addr (in network byte order) which is
	      converted to a representation of this address in the most appro‐
	      priate IPv6 network address format for this address.  The buffer
	      dst must be at least INET6_ADDRSTRLEN bytes long.

       On success, inet_ntop() returns a non-null pointer  to  dst.   NULL  is
       returned if there was an error, with errno set to indicate the error.

	      af was not a valid address family.

       ENOSPC The  converted  address  string  would  exceed the size given by

       POSIX.1-2001.  Note that RFC 2553 defines a prototype  where  the  last
       argument	 size is of type size_t.  Many systems follow RFC 2553.	 Glibc
       2.0 and 2.1 have size_t, but 2.2 and later have socklen_t.

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