ares_expand_string - Expand a length encoded string SYNOPSIS
#include <ares.h> int ares_expand_string(const unsigned char *encoded, const unsigned char *abuf, int alen, unsigned char **s, long *enclen) DESCRIPTION
The ares_expand_string function converts a length encoded string to a NUL-terminated C string. The argument encoded gives the beginning of the encoded string, and the arguments abuf and alen give the containing message buffer (necessary for the processing of indirection point- ers within the encoded domain name). The result is placed in a NUL-terminated allocated buffer, a pointer to which is stored in the vari- able pointed to by s. The length of the encoded string is stored in the variable pointed to by enclen so that the caller can advance past the encoded string to read further data in the message. RETURN VALUES
ares_expand_string can return any of the following values: ARES_SUCCESS Expansion of the encoded string succeeded. ARES_EBADSTR The encoded string was malformed and could not be expanded. ARES_ENOMEM Memory was exhausted. SEE ALSO

ares_parse_aaaa_reply - Parse a reply to a DNS query of type AAAA SYNOPSIS
#include <ares.h> int ares_parse_aaaa_reply(const unsigned char *abuf, int alen, struct hostent **host, struct ares_addr6ttl *addrttls, int *naddrttls); DESCRIPTION
The ares_parse_aaaa_reply function parses the response to a query of type AAAA into a struct hostent and/or an array of struct ares_addr6ttl. The parameters abuf and alen give the contents of the response. The result is stored in allocated memory and a pointer to it stored into the variable pointed to by host, if host is nonnull. It is the caller's responsibility to free the resulting host structure using ares_free_hostent(3) when it is no longer needed. If addrttls and naddrttls are both nonnull, then up to *naddrttls struct ares_addr6ttl records are stored in the array pointed to by addrt- tls, and then *naddrttls is set to the number of records so stored. Note that the memory for these records is supplied by the caller. RETURN VALUES
ares_parse_aaaa_reply can return any of the following values: ARES_SUCCESS The response was successfully parsed. ARES_EBADRESP The response was malformatted. ARES_ENODATA The response did not contain an answer to the query. ARES_ENOMEM Memory was exhausted. SEE ALSO
