用C语言如何查看系统盘状态。
如输入命 chkdsk后
输出系统盘（c）的存储状态等

使用相关API调用

能具体点吗？

主要API函数原型说明如下：

　　1.获取系统中逻辑驱动器的数量

The GetLogicalDrives function retrieves a bitmask representing the currently available disk drives.

DWORD GetLogicalDrives(void);
 

　　2.获取所有驱动器字符串信息

The GetLogicalDriveStrings function fills a buffer with strings that specify valid drives in the system.

DWORD GetLogicalDriveStrings(
  DWORD nBufferLength,
  LPTSTR lpBuffer
);

　　3.获取驱动器类型

The GetDriveType function determines whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive.

UINT GetDriveType(
  LPCTSTR lpRootPathName
);

　　4. 获取驱动器磁盘的空间状态,函数返回的是个BOOL类型数据

The GetDiskFreeSpaceEx function retrieves information about the amount of space available on a disk volume: the total amount of space, the total amount of free space, and the total amount of free space available to the user associated with the calling thread.

BOOL GetDiskFreeSpaceEx(
  LPCTSTR lpDirectoryName,
  PULARGE_INTEGER lpFreeBytesAvailable,
  PULARGE_INTEGER lpTotalNumberOfBytes,
  PULARGE_INTEGER lpTotalNumberOfFreeBytes
);

我完成拉！
#include <windows.h>
#include <stdio.h>

typedef BOOL (WINAPI *PGETDISKFREESPACEEX)(LPCSTR,
                                           PULARGE_INTEGER, PULARGE_INTEGER, PULARGE_INTEGER);

BOOL MyGetDiskFreeSpaceEx(LPCSTR pszDrive)
{
    PGETDISKFREESPACEEX pGetDiskFreeSpaceEx;
    __int64 i64FreeBytesToCaller, i64TotalBytes, i64FreeBytes;
   
    DWORD dwSectPerClust,
        dwBytesPerSect,
        dwFreeClusters,
        dwTotalClusters;
   
    BOOL fResult;
   
    pGetDiskFreeSpaceEx = (PGETDISKFREESPACEEX) GetProcAddress(
        GetModuleHandle("kernel32.dll"),
        "GetDiskFreeSpaceExA");
   
    if (pGetDiskFreeSpaceEx)
    {
        fResult = pGetDiskFreeSpaceEx (pszDrive,
            (PULARGE_INTEGER)&i64FreeBytesToCaller,
            (PULARGE_INTEGER)&i64TotalBytes,
            (PULARGE_INTEGER)&i64FreeBytes);
        
        // Process GetDiskFreeSpaceEx results.
        if(fResult)
        {
            printf("\n已用空间: %10.2fGB\n", (float)i64TotalBytes/(1024*1024*1024)-(float)i64FreeBytesToCaller/(1024*1024*1024));
            printf("可用空间: %10.2fGB\n", (float)i64FreeBytes/(1024*1024*1024));
            printf("总空间:   %10.2fGB\n", (float)i64TotalBytes/(1024*1024*1024));
        }
        return fResult;
    }
   
    else
    {
        fResult = GetDiskFreeSpaceA (pszDrive,
            &dwSectPerClust,
            &dwBytesPerSect,
            &dwFreeClusters,
            &dwTotalClusters);
        
        // Process GetDiskFreeSpace results.
        if(fResult)
        {
            printf("Total free bytes = I64d\n",
                dwFreeClusters*dwSectPerClust*dwBytesPerSect);
        
        }
        return fResult;
    }
}
