Parse a reply to a dns query of type naptr
#include <ares.h> int ares_parse_naptr_reply(const unsigned char* abuf, int alen, struct ares_naptr_reply** naptr_out);
The ares_parse_naptr_reply function parses the response to a query of type NAPTR into a linked list of struct ares_naptr_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 naptr_out. It is the caller's responsibility to free the resulting naptr_out structure when it is no longer needed using the function ares_free_data
The structure ares_naptr_reply contains the following fields:
struct ares_naptr_reply { struct ares_naptr_reply *next; unsigned char *flags; unsigned char *service; unsigned char *regexp; char *replacement; unsigned short order; unsigned short preference; };
ares_parse_naptr_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.
This function was first introduced in c-ares version 1.7.6.
