Re: mcicda: How can we get STATUS_XXX in GetLastError()?

Francois Gouget a écrit :
In dlls/mcicda/mcicda.c we have:
     if (!DeviceIoControl(wmcda->handle, IOCTL_CDROM_READ_Q_CHANNEL, &fmt, 
sizeof(fmt),
                          &data, sizeof(data), &br, NULL)) {
         if (GetLastError() == STATUS_NO_MEDIA_IN_DEVICE) mode = MCI_MODE_OPEN;

However DeviceIoControl() does the following:

    if (status) SetLastError( RtlNtStatusToDosError(status) );
    return !status;
}

And RtlNtStatusToDosError() converts STATUS_NO_MEDIA_IN_DEVICE to 
ERROR_NOT_READY. So GetLastError() cannot return 
STATUS_NO_MEDIA_IN_DEVICE. Or did I miss something? Maybe the right 
thing would be to check the return value of DeviceIoControl() rather 
than GetLastError()?


However, in MCICDA_GetError() we have a similar check:


 static int     MCICDA_GetError(WINE_MCICDAUDIO* wmcda)
 {
     switch (GetLastError())
     {
     case STATUS_NO_MEDIA_IN_DEVICE:     return MCIERR_DEVICE_NOT_READY;
     case STATUS_IO_DEVICE_ERROR:        return MCIERR_HARDWARE;
     default:
        FIXME("Unknown mode %x\n", GetLastError());
     }

Again, as far as I can see, GetLastError() cannot return these two 
STATUS_XXX values so this check seems wrong.


  
you're right, the NT error codes should be converted into their win32 
equivalents
