The \fBaf\fP argument shall 20 specify the family of the address. The AF_INET and AF_INET6 address families 21 shall be supported. The \fBsrc\fP argument points to the string being passed 22 in. The \fBdst\fP argument points to a buffer into which the function stores 23 the numeric address; this shall be large enough to hold the numeric address 24 (32 bits for AF_INET, 128 bits for AF_INET6). 25 26 It returns 1 if the address was valid for the specified address family, or 0 27 if the address was not parseable in the specified address family, or -1 if 28 some system error occurred (in which case errno will have been set). 29 30 .SH SEE ALSO 31 .BR ares_init (3), 32 .BR ares_inet_ntop (3) 33 .SH AVAILABILITY 34 made properly publicly available in c-ares for real in version 1.10.0 35
