ARES_INET_PTON(3) Introduction to Library Functions ARES_INET_PTON(3)

NAME

ares_inet_pton - convert an IPv4 or IPv6 address from text to binary
form

SYNOPSIS

#include <ares.h>

int ares_inet_pton(int af, const char *src, void *dst);

DESCRIPTION

This is a portable version with the identical functionality of the
commonly available inet_pton.

The ares_inet_pton() function converts the address in its standard
text presentation form into its numeric binary form. The af argument
shall specify the family of the address. The AF_INET and AF_INET6
address families shall be supported. The src argument points to the
string being passed in. The dst argument points to a buffer into
which the function stores the numeric address; this shall be large
enough to hold the numeric address (32 bits for AF_INET, 128 bits for
AF_INET6).

It returns 1 if the address was valid for the specified address
family, or 0 if the address was not parseable in the specified
address family, or -1 if some system error occurred (in which case
errno will have been set).
