ARES_PARSE_TXT_REPLY(3)                     DragonFly Library Functions Manual


NAME

       ares_parse_txt_reply - Parse a reply to a DNS query of type TXT


SYNOPSIS

       #include <ares.h>

       int ares_parse_txt_reply(const unsigned char* abuf, int alen,
       struct ares_txt_reply **txt_out);


DESCRIPTION

       The ares_parse_txt_reply function parses the response to a query of
       type TXT into a linked list (one element per sub-string) of struct
       ares_txt_reply 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 txt_out.  It is the caller's
       responsibility to free the resulting txt_out structure when it is no
       longer needed using the function ares_free_data

       The structure ares_txt_reply contains the following fields:

           struct ares_txt_reply {
             struct ares_txt_reply  *next;
             unsigned int  length;
             unsigned char *txt;
           };


RETURN VALUES

       ares_parse_txt_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.
