Hardware "initialization"

Is there a way to detect maximum and available hard drive space?

Also, is there a GetAllInputDevicesAndPrintEachToClientArea function? :-)

Seriously, I was looking at GetSystemMetrics and the mouse detection looked a little weak and was wondering if there were a more reliable way to detect it than SM_MOUSEPRESENT?

Microsoft says:

Nonzero if a mouse is installed; otherwise, 0 (zero). This value is rarely zero, because of support for virtual mice and because some systems detect the presence of the port instead of the presence of a mouse.

Code snippet below to detect maximum and available hard drive space.

Code:

---

#include <windows.h>
#include <stdio.h>

int main(void)
{
    unsigned __int64 i64TotalBytes, i64AvailableBytes;   

    BOOL  bReturn;
    char  *pDrive  = "C:\\";
    DWORD dwSectorsPerCluster,
        dwBytesPerSector,
        dwFreeClusters,
        dwTotalClusters;

    bReturn = GetDiskFreeSpace (pDrive,
        &dwSectorsPerCluster,
        &dwBytesPerSector,
        &dwFreeClusters,
        &dwTotalClusters);
    if (bReturn)
    {
        /* cast it to 64 bits for calculations */
        i64TotalBytes = (__int64)dwTotalClusters * dwSectorsPerCluster * dwBytesPerSector;
        i64AvailableBytes = (__int64)dwFreeClusters * dwSectorsPerCluster * dwBytesPerSector;
        printf ("Available = %I64u MB\n", i64AvailableBytes / (1024*1024));
        printf ("Total  = %I64u MB\n",i64TotalBytes / (1024*1024));
    }
    else
        printf("GetDiskFreeSpace failed\n");
    return 0;
}

Thanks! It works great!
