Overview
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.
