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.
