Start streaming the first "in_pFSFlags->uNumBytesPrefetch" bytes of the file with id "in_fileID" into cache. The stream will be scheduled only after all regular streams (not file caching streams) are serviced. The file will stay cached until either the UnpinFileInCache is called, or the limit as set by uMaxCachePinnedBytes is reached and another higher priority file (in_uPriority) needs the space.
