谁知道IOCTL_STORAGE_CHECK_VERIFY的值；急急！ (50分)

有谁知道：IOCTL_STORAGE_CHECK_VERIFY <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;IOCTL_STORAGE_EJECT_MEDIA <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;IOCTL_STORAGE_GET_MEDIA_TYPES <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;IOCTL_STORAGE_LOAD_MEDIA <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;IOCTL_STORAGE_MEDIA_REMOVAL <br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 这几个参数的值？<br>&nbsp; &nbsp; &nbsp;重要的是IOCTL_STORAGE_CHECK_VERIFY，其它能说就说吧！<br>只有50分，急呀！

说清楚亚

也就是DeviceIoControl API中的那几个参数呀！！

NowCan：<br>&nbsp; &nbsp; 真是谢谢了！<br>&nbsp; &nbsp; 不知那位大哥懂C，解释一下嘛！完全看不懂！：》

简单的说一下嘛！例如：<br>#define CTL_CODE( DeviceType, Function, Method, Access ) ( &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; /<br>&nbsp; &nbsp; ((DeviceType) &lt;&lt; 16) | ((Access) &lt;&lt; 14) | ((Function) &lt;&lt; 2) | (Method) /<br>)<br>这是什么！是函数吗？下面的那些‘《’是什么意思！<br>

这个是宏，&lt;&lt;是左移(不带进位位)，|是二进制或，但我不知道Delphi里怎么写。<br>你可以看成函数<br>它的参数就是那4个<br>返回值就是((DeviceType) &lt;&lt; 16) | ((Access) &lt;&lt; 14) | ((Function) &lt;&lt; 2) | (Method) <br><br>例如<br><br>#define IOCTL_STORAGE_CHECK_VERIFY &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;CTL_CODE(IOCTL_STORAGE_BASE, 0x0200, METHOD_BUFFERED, FILE_READ_ACCESS)<br>就是<br>IOCTL_STORAGE_BASE是0x0000002d，左移16位=0x2d0000<br>0x0200左移14位＝0x800000<br>METHOD_BUFFERED是0，左移2位＝0<br>FILE_READ_ACCESS是0x0001<br>最后或一下就得到最后结果00xad0001

不知道有没有算对。

实在多谢了！
