.SH DESCRIPTION
|
|
|
|
|
This is a portable version with the identical functionality of the commonly
|
|
|
|
|
available \fIinet_ntop\fP.
|
|
|
|
|
|
|
|
|
|
The ares_inet_ntop() function converts a numeric address into a text string
|
|
|
|
|
suitable for presentation. The \fBaf\fP argument shall specify the family of
|
|
|
|
|
the address. This can be AF_INET or AF_INET6. The \fBsrc\fP argument points
|
|
|
|
|
to a buffer holding an IPv4 address if the af argument is AF_INET, or an IPv6
|
|
|
|
|
address if the af argument is AF_INET6; the address must be in network byte
|
|
|
|
|
order. The \fBdst\fP argument points to a buffer where the function stores the
|
|
|
|
|
resulting text string; it shall not be NULL. The \fBsize\fP argument specifies
|
|
|
|
|
the size of this buffer, which shall be large enough to hold the text string
|
|
|
|
|
(INET_ADDRSTRLEN (16) characters for IPv4, INET6_ADDRSTRLEN (46) characters
|
|
|
|
|
for IPv6).
