+ 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.
