NAME
ares_expand_string - Expand a length encoded string
SYNOPSIS
#include <ares.h>
int ares_expand_string(const unsigned char *encoded,
const unsigned char *abuf, int alen, unsigned char **s,
long *enclen)
DESCRIPTION
The ares_expand_string function converts a length encoded string to a
NUL-terminated C string. The argument encoded gives the beginning of
the encoded string, 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-termi-
nated allocated buffer, a pointer to which is stored in the variable
pointed to by s. The length of the encoded string is stored in the
variable pointed to by enclen so that the caller can advance past the
encoded string to read further data in the message.
RETURN VALUES
ares_expand_string can return any of the following values:
ARES_SUCCESS Expansion of the encoded string succeeded.
ARES_EBADSTR The encoded string was malformed and could not be
expanded.
ARES_ENOMEM Memory was exhausted.
