Hi Simon,
Can we add some documentation here? I don't find that the comment in
the implementation is clear enough.

+ /* Convert an internet address from a printable, presentable format to

+ format.
+ AF is an internet address family, such as AF_INET or AF_INET6.
+ SRC points to a printable representation of the address (in numeric form,
not
+ surrounded by [...], no DNS lookup is done).
+ DST points to a 'struct in_addr' (for AF_INET) or 'struct in6_addr'
+ (for AF_INET6).
+ If the string at SRC is a valid printable representation of an address of
the
+ given family, store the internal format of the address at DST and return 1.
+ If it is invalid, return 0. Upon error, set errno and return -1. */
