ares_expand_string - Expand a length encoded string
int ares_expand_string(const unsigned char *encoded,
const unsigned char *abuf, int alen, unsigned char **s,
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
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 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.
can return any of the following values:
- Expansion of the encoded string succeeded.
- The encoded string was malformed and could not be
- Memory was exhausted.
