I would like to write my own version of Microsoft Live labs pivot.http://www.getpivot.com/
For this i will use realtime texture streaming technology like John Carmack did for doom4.

But i would like to use Windows vista SetFileBandwidthReservation api to have the best throughput possible.

For example

// reserve bandwidth of 200 bytes/sec
result = SetFileBandwidthReservation( hFile,
1000,
200,
FALSE,
&transferSize,
&outstandingRequests );

What i dont understand is the lpTransferSize and lpNumOutstandingRequests return parameters.
How should i next read the file for this to be the most worth it.

Should i do exactly lpNumOutstandingRequests number of request of size lpTransferSize.
Or can i do one synchronous request bigger than lpTransferSize.
