获取磁碟详细信息的问题

[NorthPBear]

小弟写了一段 关于获取计算机 磁碟信息的代码
想通过如下代码 实现 分辨 硬盘 优盘 光驱等等

int GetLogiDrv()
{
int DrivesCount=0; //磁碟计数器
DWORD DrivesInfo=GetLogicalDrives();
while (DrivesInfo)
{
if (DrivesInfo&1)
DrivesCount++;
DrivesInfo=DrivesInfo>>1; //向右偏移1位,读取下一位.
}
cout<<"当前逻辑驱动器数量是:"<<DrivesCount<<endl;
return (0);
}

int GetLogiDrvTp()
{
DWORD LogiDrvStrInfo=GetLogicalDriveStrings(0,NULL);
cout<<"当前驱动器字符串信息是:"<<LogiDrvStrInfo<<endl;
char* TpInfo=new char[LogiDrvStrInfo]; //在堆区建立字符传数组;

GetLogicalDriveStrings(LogiDrvStrInfo,TpInfo); //拷贝到TpInfo中

int DrvType=GetDriveType(TpInfo);
cout<<"当前驱动器标识代号是:"<<DrvType<<endl;
//3是硬盘,5是光驱;
return (0);
}

int GetDrvSpa()
{
// float DrvSpa=GetDiskFreeSpaceEx();
return (0);
}

main ()
{
CopyRight();
GetLogiDrv();
GetLogiDrvTp();
}



但是发现 似乎输出的不太对.
还有就是 如何获取获取磁盘剩余空间信息

请教高人

用DeviceIocontrol发送命令获取，但是前提是要知道它的HANDLE.

GetDiskFreeSpace() 
或者 
GetDiskFreeSpaceEx() 

具体用法查一查参考手册或者帮助文件

没什么问题啊

#include "windows.h"
#include "iostream"
using namespace std;

int GetLogiDrv() 
{ 
    bool drives[32] = { false };
    int  i = 0;

    int DrivesCount=0; //磁碟计数器 
    DWORD DrivesInfo=GetLogicalDrives(); 
    while (DrivesInfo) 
    { 
        if (DrivesInfo&1) 
        {
            DrivesCount++; 
            drives[i] = true;
        }
        i++;
        DrivesInfo=DrivesInfo>>1; //向右偏移1位,读取下一位. 
        
    } 
    cout<<"当前逻辑驱动器数量是:" <<DrivesCount<<" (";
    for (i = 0; i < 32; ++i)
        if (drives[i])
            cout<<(char)('A' + i)<<":  ";
    cout<<" )"<<endl;

    return (0); 
} 

int GetLogiDrvTp() 
{ 
    DWORD LogiDrvStrInfo=GetLogicalDriveStrings(0,NULL); 

    char* TpInfo=new char[LogiDrvStrInfo]; //在堆区建立字符传数组; 

    GetLogicalDriveStrings(LogiDrvStrInfo,TpInfo); //拷贝到TpInfo中 
    cout <<"当前驱动器字符串信息是:" <<TpInfo <<endl; 
    int DrvType=GetDriveType(TpInfo); 
    cout <<"当前驱动器标识代号是:" <<DrvType <<endl; 
    //3是硬盘,5是光驱; 
    return (0); 
} 

int GetDrvSpa() 
{ 
    float DrvSpa=GetDiskFreeSpaceEx(); 
    return (0); 
} 

int main () 
{ 
    //CopyRight(); 
    GetLogiDrv(); 
    GetLogiDrvTp(); 
    return 0;
}

GetDiskFreeSpace();

用法查msdn吧
