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;
           };
