NAME
       iob_prefetch - prefetch data for I/O batch

SYNTAX
       #include <iob.h>

       void iob_prefetch(io_batch* b,uint64 n);

DESCRIPTION
       iob_prefetch makes sure the next n bytes are in memory.

       This  is useful when serving large files over the network concurrently.
       Prefetching the data can	 then  reduce  hard  disk  head	 movement  and
       enhance throughput.
