ARES_PARSE_A_REPLY(3) Library Functions Manual ARES_PARSE_A_REPLY(3) NAME ares_parse_a_reply - Parse a reply to a DNS query of type A SYNOPSIS #include <ares.h> int ares_parse_a_reply(const unsigned char *abuf, int alen, struct hostent **host, struct ares_addrttl *addrttls, int *naddrttls); DESCRIPTION The ares_parse_a_reply function parses the response to a query of type A into a struct hostent and/or an array of struct ares_addrttls. 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 vari- able 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_addrttl records are stored in the array pointed to by addrttls, 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_a_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.
