ntddscsi.h

/*
 * borrowed from http://members.aol.com/plscsi/tools/gccscsi/
 *
 * ntddscsi.h
 *
 * This source file for Win 2K/XP exists to make:
 *
 *  #include "ntddscsi.h"
 *
 * work, with both Microsoft Visual C++, and
 * also in the gcc of:
 *
 *  http://www.mingw.org/
 *
 * Most of the names and the values equated here
 * match those you can find in the version of
 * Microsoft's "ntddk/inc/ntddscsi.h" that is tagged:
 *
 *  BUILD Version: 0001
 *  Copyright (c) 1990-1999  Microsoft Corporation
 *
 * That version in turn matches what you can view
 * in such places as:
 *
 *  Windows DDK: System Support for Buses: DeviceIoControl struct SCSI_PASS_THROUGH
 *  http://msdn.microsoft.com/library/en-us/buses/hh/buses/scsi_struct_34tu.asp
 *
 *  Windows DDK: System Support for Buses: DeviceIoControl struct SCSI_PASS_THROUGH_DIRECT
 *  http://msdn.microsoft.com/library/en-us/buses/hh/buses/scsi_struct_3qnm.asp
 *
 * Microsoft's ntddk/ version is more complete.  This
 * version contains just enough names to make
 * DeviceIoControl work, and may be more closely
 * tied to the 32-bit versions of Windows.
 *
 * Microsoft's version also implicitly depends on:
 *
 *  #include <devioctl.h>
 *
 * We did try the alternative: -I /ntddk/inc/
 * but we saw an explosion of gcc -Wall complaints
 * in <ctype.h>, in <jni.h>, etc.
