使用GetLogicalDriveStrings获取驱动器根路径

使用GetLogicalDriveStrings获取驱动器根路径，并使用自定义的GetDriveInfo函数获取驱动器的属性。

VS2012 + win7 x64下调试通过。

#include <Windows.h>
#include <stdio.h>
#include <stdlib.h>
#define BUFSIZE 1024
BOOL GetDriverInfo(LPSTR szDrive);
//int WinMain(HINSTANCE hInstance,HINSTANCE hPreInstance,LPSTR lpCmdLine,int nCmdShow)
int main(void)
{
    CHAR szLogicDriveStrings[BUFSIZE];
    PCHAR szDrive;

    ZeroMemory(szLogicDriveStrings,BUFSIZE);

    GetLogicalDriveStrings(BUFSIZE-1,szLogicDriveStrings);
    szDrive = (PCHAR)szLogicDriveStrings;

    do 
    {
        if(!GetDriverInfo(szDrive))
        {
            printf("

        }
