NAME

       lc_hashtoaddr - create IPv6 multicast addr from supplied hash and flags

LIBRARY

       Librecast library (liblibrecast, -llibrecast)

SYNOPSIS

       #include <librecast/net.h>

       void lc_hashtoaddr(struct in6_addr *addr, unsigned char *hash, size_t hashlen,
                          unsigned char flags);

       Compile and link with -llibrecast.

DESCRIPTION

       The lc_hashtoaddr() function creates and returns an IPv6 multicast address in addr from the supplied hash
       of length hashlen and flags.

       The  address  returned  in  addr  is  a  valid IPv6 multicast address. The first 8 bits are set to 1. The
       following 8 bits are set to flags, which should be the valid IPv6 multicast 4 bit flags field as  defined
       in  IETF  RFC  4291, followed by the 4 bits for multicast scope.  The first 14 bytes of hash are used for
       the remaining 14 bytes of the address.

RETURN VALUE

       The lc_hashtoaddr () function returns no value.

ERRORS

       None.
