使用Win32 API安全地删除一个USB驱动器?

How do I remove a USB drive using the Win32 API? I do a lot of work on embedded systems and on one of these I have to copy my programs on a USB stick and insert it into the target hardware.

如何使用Win32 API删除USB驱动器?我在嵌入式系统上做了很多工作，其中之一就是把我的程序复制到USB上，然后插入目标硬件。

Since I mostly work on the console I don't like to use the mouse and click on the small task-bar icon hundred times a day.

由于我主要在控制台工作，所以我不喜欢每天使用鼠标点击小任务栏图标上百次。

I'd love to write a little program to do exactly that so I can put it into my makefiles, but I haven't found any API call that does the same thing.

我很想写一个小程序来实现这一点，这样我就可以把它放到我的makefile中，但是我还没有找到任何做同样事情的API调用。

Any ideas?

什么好主意吗?

It looks like Sync lets you specify -e to eject removable drives. While not a win32 API, you could probably just call sync -e [drive_letter] from your makefile.

看起来同步允许你指定-e来弹出可移动驱动器。虽然不是win32 API，但您可以从makefile中调用sync -e [drive_letter]。

Here's a solution in Delphi, that I've modified and put into a service for use in a very large enterprise. Go to: link text

在Delphi中有一个解决方案，我对它进行了修改，并将其放入服务中，以便在大型企业中使用。去:链接文本

Look for "scapi (Setup & Config Manager API)", and download it. There will be a demo program called USBView that will get you on your way. If you have Delphi, this also includes a TUSBDeviceTree component that you can use to gather information about a USB device when.

查找“scapi(设置和配置管理器API)”,下载它。将会有一个叫做USBView的演示程序，它会带你上路。如果您有Delphi，这还包括一个TUSBDeviceTree组件，您可以使用它来收集关于USB设备的信息。
