如何从驱动器号获取驱动器名称？

Question

我已经搜索了互联网，但找不到答案，如何从Windows的c ++的驱动器号中获取驱动器名称？我的意思是如果我说G：\\，它必须给我笔驱动器的名称。例如：可移动磁盘。

It is as simple as calling the GetVolumeInformation API function . You pass in the drive letter as the path name ( eg , G:\\ ), and the function fills a buffer containing the volume name (along with other information, if you are interested in any of that).

Here is the code required to retrieve the volume name for the G:\\ drive. The volume name is placed into the szVolumeName buffer:

WCHAR szVolumeName[MAX_PATH];
BOOL bSucceeded = GetVolumeInformationW(L"G:\\",
                                        szVolumeName,
                                        MAX_PATH,
                                        NULL,
                                        NULL,
                                        NULL,
                                        NULL,
                                        0);

If you want any of the other information while you're calling the function, like the volume's DOS serial number, the file system name, etc., then you can change the parameters from NULL to the appropriate buffers.
