Parameters

`hRTCommandQueue`

The handle of the command queue for the driver to use when it calls back into the runtime.

`unnamedParam2`

Pointer to a D3DDDICB_CREATEHWQUEUE structure that contains information needed to create a hardware queue.

Return value

Returns HRESULT.

Remarks

Destroys are not provided for these objects, as their lifetime is completely managed by the owning runtime object. Validation will be in place that hardware queue creation must be done against a context either associated with the same command queue, or with a parent scheduling group. The driver is allowed to create hardware queues which reference both types of contexts for a single CreateCommandQueue. The CreateCommandQueue callback is reviewed so the driver is informed of this relationship.
