获取可用的驱动器及其大小的列表 [英] Get a list of the available drives and their sizes

问题描述

我知道你可以使用GetLogicalDrives（）和GetDiskFreeSpaceEx（）的组合来获取驱动器及其大小的列表。我一直在使用GetDiskFreeSpaceEx（），没有问题，但是当我尝试使用GetLogicalDrives（）我遇到了一个问题：我不希望有检查每一个可能的字母，看看它是否存在与否它传递给GetDiskFreeSpaceEx前（）

I know you can use a combination of GetLogicalDrives() and GetDiskFreeSpaceEx() to get the list of drives and their sizes. I've been using GetDiskFreeSpaceEx() with no problem but when I try to use GetLogicalDrives() I ran into a problem: I don't want to have to check each possible letter to see whether it exists or not before passing it to GetDiskFreeSpaceEx().

有没有一种简单的方法来获得系统的驱动器（硬盘）的名单，以及他们的大小？我使用C，在Windows上。

Is there a simpler way to get the list of drives (disk) on the system and what their sizes are? I am using C, on Windows.

我想做出点清楚，我的了解可能使用C＃和WMI更容易，我对那个没兴趣，所以请不要张贴，作为一个可能的解决方案。如果你想指向C和WMI是如何做的，去了。没有C ++或C＃的感谢！ （就像有人在<一做href=\"http://stackoverflow.com/questions/2238606/how-to-check-whether-windows-file-indexing-is-on-or-off\">my previous问题）

I want to make something clear, I KNOW it might be easier using C# and WMI, I have no interest on that so please do not post that as a possible solution. If you want to point to how is done in C and WMI, go for it. NO C++ or C# thanks! (like someone did in my previous question)

推荐答案

GetLogicalDrives（）是该系统提供的API。一个简单的for（）循环将其结果转化为驱动器盘符，如：

GetLogicalDrives() is the system-provided API for that. A simple for() loop will translate its result into drive letters, like this:

DWORD d = GetLogicalDrives();
int i;
TCHAR Drive[] = _T("A:\\");
for(i=0;i<26;i++)
{
    if(d & (1<<i))
    {
        Drive[0] = _T('A')+i;
        GetDiskFreeSpaceEx(Drive, .....);
    }
}
