NAME
ares_expand_string - Expand a length encoded stringSYNOPSIS
#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-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.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.
