/* Converts an internet address from internal format to a printable,
   presentable format.
   AF is an internet address family, such as AF_INET or AF_INET6.
   SRC points to a 'struct in_addr' (for AF_INET) or 'struct in6_addr'
   (for AF_INET6).
   DST points to a buffer having room for CNT bytes.
   The printable representation of the address (in numeric form, not
   surrounded by [...], no reverse DNS is done) is placed in DST, and
   DST is returned.  If an error occurs, the return value is NULL and
   errno is set.  If CNT bytes are not sufficient to hold the result,
   the return value is NULL and errno is set to ENOSPC.  A good value
   for CNT is 46.

   For more details, see the POSIX:2008 specification
   <https://pubs.opengroup.org/onlinepubs/9699919799/functions/inet_ntop.html>.  */
