在本地计算机上获取可用的物理驱

Question

I am trying to get all the physical drives available on local machine. I tried to use GetLogicalDrives() but when i'm using this function it gets me also drives that physically not available on the machine, for example floppy drive A. Here is my code:

void FindDrives()
{
    DWORD drives = GetLogicalDrives();
     for (int i=0; i<26; i++)
     {
        if( ( drives & ( 1 << i ) ) )
        {
           wchar_t driveName[] = { L'A' + i, L':', L'\\', L'\0'};
           std::wcout << driveName << std::endl;
        }
     }
}

How can I get only physically available drives?

Try using wmic

wmic diskdrive list

for less info

wmic diskdrive list brief 

Alternatively in c use GetLogicalDrives() first to get all of the drives mapped in the system, and then GetDriveType() to find out which sort of drive each one is. Then sort it out as you want to.
