    ReactOS
    Kernel Streaming API
 
    by Andrew Greenwood
 
    NOTES:
    This is a basic stubbing of the Kernel Streaming API header. It is
    very incomplete - a lot of the #defines are not set to any value at all.
 
    Some of the structs/funcs may be incorrectly grouped.
 
    GUIDs need to be defined properly.
 
    AVStream functionality (XP and above, DirectX 8.0 and above) will NOT
    implemented for a while.
 
    Some example code for interaction from usermode:
    DeviceIoControl(
        FilterHandle,
        IOCTL_KS_PROPERTY,
        &Property,
        sizeof(KSPROPERTY),
        &SeekingCapabilities,
        sizeof(KS_SEEKING_CAPABILITIES),
        &BytesReturned,
        &Overlapped);
