AcxDrmForwardContentToDeviceObject function (acxstreams.h)
The AcxDrmForwardContentToDeviceObject function accepts a device object representing a device to which the caller intends to forward protected content. The function authenticates the device and sends it the content ID and DRM rights that the system has assigned to the protected content.

ULONG ContentId,
PVOID Reserved,
PCACXDRMFORWARD DrmForward
);
Parameters
ContentId
Specifies a nonzero DRM content ID assigned to an ACX audio stream by AcxDrmCreateContentMixed. Note that a content ID of zero represents an audio stream with default DRM content rights, and cannot be used with this function.

DrmForward
Pointer to an ACXDRMFORWARD structure specifying a device object and file object that identify the target device and a KS audio pin on that device, respectively. The structure also contains the context value that the KSPROPERTY_DRMAUDIOSTREAM_CONTENTID set-property request passes to the device.
