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.
