如果您想在 Windows 上使用 MSVC 获取驱动器控制器,则可以使用 GetLogicalDrives 函数。此函数返回一个 32 位整数,其中每个比特位都表示系统的一个逻辑驱动器。比特位为 1 表示相应的驱动器存在,而比特位为 0 表示相应的驱动器不存在。
您可以使用以下示例代码来获取系统上所有的逻辑驱动器:
```c++
#include <windows.h>
#include <iostream>
int main()
{
DWORD logicalDrives = GetLogicalDrives();
for (char i = 'A'; i <= 'Z'; i++)
{
if (logicalDrives & 1)
{
std::cout << i << " drive exists." << std::endl;
}
else
{
std::cout << i << " drive does not exist." << std::endl;
}
logicalDrives >>= 1;
}
return 0;
}
```
这将打印类似以下内容的输出:
```
A drive exists.
B drive does not exist.
C drive exists.
D drive does not exist.
E drive exists.
F drive exists.
G drive does not exist.
H drive does not exist.
I drive does not exist.
J drive does not exist.
K drive does not exist.
L drive does not exist.
M drive does not exist.
N drive does not exist.
O drive does not exist.
P drive does not exist.
Q drive does not exist.
R drive does not exist.
S drive does not exist.
T drive does not exist.
U drive does not exist.
V drive does not exist.
W drive does not exist.
X drive does not exist.
Y drive does not exist.
Z drive does not exist.
```
请注意,该函数只能检测到逻辑驱动器,而不是物理驱动器。此外,对于某些网络驱动器,此函数可能返回错误的结果。
