/* 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.
