Module Name:

    io.c

Abstract:

    This file contains the procedures to process I/O requests from
    a User Mode entity.  All OS dependent I/O interface functions
    will be conditionally coded, and will be responsible for translating
    the I/O functions from the OS format to buffers that are useable by
    the main I/O handling routine.
