This structure is used to describe the request parameters for

|
|
|
|
Members:
|
|
|
|
LeaseStartTime - desired start time of the lease, pass 0 if desired start time
|
|
is current time. The desired time is specified in the number of seconds elapsed
|
|
since midnight (00:00:00), January 1, 1970, coordinated universal time.
|
|
|
|
MaxLeaseStartTime - the maximum start time that the client is willing to accept.
|
|
Where time is the number of seconds elapsed since midnight (00:00:00),
|
|
January 1, 1970, coordinated universal time.
|
|
|
|
LeaseDuration - desired lease time for the request, pass 0 if default
|
|
lease time is requested.
|
|
|
|
MinLeaseDuration - the minimum lease time that the client is willing
|
|
to accept
|
|
|
|
ServerAddress - server's ip address where this lease whas renewed/requested.
|
|
pass 0 if unknown (e.g in McastRequestAddress)
|
|
|
|
MinAddrCount - minimum number of addresses that the client is willing
|
|
to accept
|
|
|
|
AddrCount - the desired number of addresses requested/allocated/renewed.
|
|
This also specifies the size of the array specified by Addr.
|
|
|
|
pAddrBuf - buffer containing specific addresses being requested/renewed/released.
|
|
For IPv4 it is a pointer to 4 byte addresses and for IPv6 it
|
|
points to 16 byte chunks. Pass NULL if no specific addresses
|
|
are requested.
|
|
|
|
Remarks:
|
|
|
|
In MCAST_API_VERSION_1 version, the MaxLeaseStartTime, MinLeaseDuration and
|
|
MinAddrCount are ignored by the API implementation. However, the clients should
|
|
set appropriate desired values for these members so as when the OS update brings
|
|
new implementation of the APIs then the clients can take advantage of it.
