如何在DeleteVolumeMountPoint之後恢復驅動器掛載？

Question

使用DeleteVolumeMountPoint（「E：\」）（例如）爲了刪除一個DOK的掛載點後，我想恢復它。 （使驅動器號再次可用）

我該怎麼做？

查看DeleteVolumeMountPoint的MSDN文檔說，SetVolumeMountPoint將完成此任務。

文檔links to an example：

#define _WIN32_WINNT 0x0501 

#include <windows.h> 
#include <tchar.h> 
#include <stdio.h> 

#define BUFSIZE MAX_PATH 

int _tmain(int argc, TCHAR *argv[]) 
{ 
    BOOL bFlag; 
    TCHAR Buf[BUFSIZE];  // temporary buffer for volume name 

    if(argc != 3) 
    { 
     _tprintf(TEXT("Usage: %s <mount_point> <volume>\n"), argv[0]); 
     _tprintf(TEXT("For example, \"%s c:\\mnt\\fdrive\\ f:\\\"\n"), argv[0]); 
     return(-1); 
    } 

    // We should do some error checking on the inputs. Make sure there 
    // are colons and backslashes in the right places, and so on 

    bFlag = GetVolumeNameForVolumeMountPoint(
       argv[2], // input volume mount point or directory 
        Buf, // output volume name buffer 
       BUFSIZE // size of volume name buffer 
      ); 

    if (bFlag != TRUE) 
    { 
     _tprintf(TEXT("Retrieving volume name for %s failed.\n"), argv[2]); 
     return (-2); 
    } 

    _tprintf(TEXT("Volume name of %s is %s\n"), argv[2], Buf); 
    bFlag = SetVolumeMountPoint(
       argv[1], // mount point 
        Buf // volume to be mounted 
      ); 

    if (!bFlag) 
    _tprintf (TEXT("Attempt to mount %s at %s failed.\n"), argv[2], argv[1]); 

    return (bFlag); 
}
