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.
