本文通过一个C++示例程序展示了如何枚举计算机上从C盘到Z盘的所有磁盘符号，并使用Windows API函数QueryDosDevice获取每个磁盘符对应的设备路径。

#include <string.h>
#include <Windows.h>
#include <tchar.h>
#include <stdio.h>
int _tmain (int argc, _TCHAR * argv[])
{
         TCHAR drv = 0;
         TCHAR cDiskSymbol [] = _T( "C:");
         for(drv =_T( 'C'); drv <= _T( 'Z'); drv ++)
        {
                 cDiskSymbol[0] = drv ;
                {
                         TCHAR szBuf [MAX_PATH] = { 0 };
                         QueryDosDevice(cDiskSymbol , szBuf, MAX_PATH);
                         _tprintf(_T ("==== %s === %s  ===\n"), cDiskSymbol , szBuf);
                }
        }
         getchar();
         return 0;
}
