The McastRenewAddress function renews one or more multicast addresses from a MADCAP server.
Syntax
DWORD McastRenewAddress(
[in] IP_ADDR_FAMILY AddrFamily,
[in] LPMCAST_CLIENT_UID pRequestID,
[in] PMCAST_LEASE_REQUEST pRenewRequest,
[in, out] PMCAST_LEASE_RESPONSE pRenewResponse
);
Parameters
[in] AddrFamily
Designates the address family. Use AF_INET for Internet Protocol version 4 (IPv4), and AF_INET6 for Internet Protocol version 6 (IPv6).
[in] pRequestID
Unique identifier used when the address or addresses were initially obtained.
[in] pRenewRequest
Pointer to the MCAST_LEASE_REQUEST structure containing multicast renew–request parameters.
[in, out] pRenewResponse
Pointer to a buffer containing response parameters for the multicast address–renew request, in the form of an MCAST_LEASE_RESPONSE structure. The caller is responsible for allocating sufficient buffer space for the pAddrBuf member of the MCAST_LEASE_RESPONSE structure to hold the requested number of addresses; the caller is also responsible for setting the pointer to that buffer.
Return value
The McastRenewAddress function returns the status of the operation.
