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 point- ers within the encoded domain name). The result is placed in a NUL-terminated allocated buffer, a pointer to which is stored in the vari- able 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. SEE ALSO

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. SEE ALSO
