CeGetDiskFreeSpaceEx - II

This is not an ActiveSync issue: my iPAQ 2210 does not support this API nor do some Windows CE 5.0-based GPS devices I've been working with. At the end of the day, I had to write a RAPI DLL to support this. The code is quite simple:

typedef struct _DISKSPACE
{
    ULARGE_INTEGER uliFreeUser,
                   uliTotalSize,
                   uliTotalFree;
} DISKSPACE;

__declspec(dllexport)
int DevGetDiskFreeSpace(DWORD cbInput, BYTE* pInput,
                        DWORD* pcbOutput, BYTE** ppOutput,
                        LPVOID pReserved)
{
    DISKSPACE ds;
    BOOL      bOk;

    bOk = GetDiskFreeSpaceEx((LPCTSTR)pInput, &ds.uliFreeUser,
                              &ds.uliTotalSize, &ds.uliTotalFree);
    if(bOk)
    {
        *ppOutput = (BYTE*)LocalAlloc(LPTR, sizeof(ds));
        memcpy(*ppOutput, &ds, sizeof(ds));
        *pcbOutput = sizeof(ds);
    }

    return 0;
}

Of course, you need to put this in a device DLL and consume it as a blocking RAPI call.
