ACX_RT_STREAM_CALLBACKS structure (acxstreams.h)
The ACX_RT_STREAM_CALLBACKS structure defines callbacks for RT streaming to the ACX framework.
Syntax
typedef struct _ACX_RT_STREAM_CALLBACKS {
ULONG Size;
PFN_ACX_STREAM_GET_HW_LATENCY EvtAcxStreamGetHwLatency;
PFN_ACX_STREAM_ALLOCATE_RTPACKETS EvtAcxStreamAllocateRtPackets;
PFN_ACX_STREAM_FREE_RTPACKETS EvtAcxStreamFreeRtPackets;
PFN_ACX_STREAM_SET_RENDER_PACKET EvtAcxStreamSetRenderPacket;
PFN_ACX_STREAM_GET_CURRENT_PACKET EvtAcxStreamGetCurrentPacket;
PFN_ACX_STREAM_GET_CAPTURE_PACKET EvtAcxStreamGetCapturePacket;
PFN_ACX_STREAM_GET_PRESENTATION_POSITION EvtAcxStreamGetPresentationPosition;
} ACX_RT_STREAM_CALLBACKS, *PACX_RT_STREAM_CALLBACKS;
Members
Size
The length, in bytes, of this structure.
EvtAcxStreamGetHwLatency
The EvtAcxStreamGetHwLatency callback.
EvtAcxStreamAllocateRtPackets
The EvtAcxStreamAllocateRtPackets callback.
EvtAcxStreamFreeRtPackets
The EvtAcxStreamFreeRtPackets callback.
EvtAcxStreamSetRenderPacket
The EvtAcxStreamSetRenderPacket callback.
EvtAcxStreamGetCurrentPacket
The EvtAcxStreamGetCurrentPacket callback.
EvtAcxStreamGetCapturePacket
The EvtAcxStreamGetCapturePacket callback.
EvtAcxStreamGetPresentationPosition
The EvtAcxStreamGetPresentationPosition callback.
Remarks
The driver must also define and use the ACX_STREAM_CALLBACKS structure to create an ACXRTSTREAM.
