函数原型：

BOOL DeleteVolumeMountPoint(

                                                      LPCTSTR lpszVolumeMountPoint  // volume mount point path

                                                   );

参数：

lpszVolumeMountPoint  ：挂载点路径，必须以反斜杠'\'结尾。

[in] Pointer to a string that indicates the volume mount point to be unmounted. This may be a root directory (X:\, in which case the DOS drive letter assignment is removed) or a directory on a volume (X:\mnt\). A trailing backslash is required.

Remarks

It is not an error to attempt to unmount a volume from a volume mount point when there is no volume actually mounted at that volume mount point.

举例说明：

//删除上一节子为F盘设置的挂载点C:\\share\\CHAR szVolumeMountPoint[] = "C:\\share\\";BOOL bRet = DeleteVolumeMountPoint(szVolumeMountPoint);if (bRet){        printf("success");       //............}
