ares_expand_name
ARES_EXPAND_NAME(3) Library Functions Manual ARES_EXPAND_NAME(3)
NAME
ares_expand_name - Expand a DNS-encoded domain name
SYNOPSIS
#include <ares.h>
int ares_expand_name(const unsigned char *encoded,
const unsigned char *abuf, int alen, char **s,
long *enclen)
DESCRIPTION
The ares_expand_name function converts a DNS-encoded domain name to a dot-separated C string. The argument encoded gives the beginning of
the encoded domain name, and the arguments abuf and alen give the containing message buffer (necessary for the processing of indirection
pointers within the encoded domain name). The result is placed in a NUL-terminated allocated buffer, a pointer to which is stored in the
variable pointed to by s. The length of the encoded name is stored in the variable pointed to by enclen so that the caller can advance
past the encoded domain name to read further data in the message.
RETURN VALUES
ares_expand_name can return any of the following values:
ARES_SUCCESS Expansion of the encoded name succeeded.
ARES_EBADNAME The encoded domain name was malformed and could not be expanded.
ARES_ENOMEM Memory was exhausted.
