| uint32_t NvSciStreamEvent::count |
Used with events that require a count.
For SyncCount, indicates the number of available sync desc to be queried, as SyncDesc events, by consumer or producer.
For PacketElementCountProducer, indicates the number of elements per packet producer will provide.
For PacketElementCountConsumer, indicates the number of elements per packet consumer could accept.
For PacketElementCount, indicates the number of packet elements determined by the pool.
Definition at line 360 of file nvscistream.h.
| NvSciError NvSciStreamEvent::error |
Used with PacketStatus and ElementStatus events.
Provides the status code.
Definition at line 336 of file nvscistream.h.
| uint32_t NvSciStreamEvent::index |
Used with events that require an index.
For ElementStatus, indicates the element for which the status is provided.
Definition at line 344 of file nvscistream.h.
| NvSciStreamElementAttr NvSciStreamEvent::packetAttr |
Used with PacketAttrConsumer, PacketAttrProducer, and PacketAttr.
Received by pool when producer and consumer specify their packet capabilities and requirements, respectively, and by the producer and consumer when the pool specifies the final packet setup.
Components in the stream may modify the attributes specified by each endpoint before they are received by the other endpoint.
In particular, multi-cast components will combine the packet requests of all consumer(s) before sending them to the producer, and IPC components which perform a copy may replace requirements on the type of memory used with their own.
The recipient owns the memory attribute handles in the event and is responsible for freeing them when no longer needed.
Definition at line 297 of file nvscistream.h.
| NvSciStreamCookie NvSciStreamEvent::packetCookie |
Used with PacketDelete, PacketStatus, and PacketElement events.
Identifies the packet to which the event refers.
Definition at line 329 of file nvscistream.h.
| NvSciStreamPacket NvSciStreamEvent::packetCreate |
Used with PacketCreate events.
Received by producer and consumer when a packet is added to the pool.
The handle provided will be valid, and should be used whenever the component references the packet in the future.
The recipient owns the memory buffer handles in the event and is responsible for freeing them when no longer needed.
Definition at line 311 of file nvscistream.h.
| NvSciStreamElementDesc NvSciStreamEvent::packetElement |
Used with PacketElement events.
Received by producer and consumer.
After receiving a PacketCreate event, producer and consumer will receive [number of packet elements] PacketElement events.
The buffer belongs to the handle specified.
Definition at line 322 of file nvscistream.h.
| NvSciStreamSyncAttr NvSciStreamEvent::syncAttr |
Used with SyncAttr events.
Received by producer and consumer, this contains the requirements for sync objects to be usable by the other endpoint(s).
Components in the stream may modify the attributes specified by each endpoint before they are received by the other endpoint. In particular, multi-cast components combine the requirements of all consumers before sending to the producer, and IPC components may replace the sync requirements if they must copy the data.
The recipient owns the memory attribute handles in the event and is responsible for freeing them when no longer needed.
Definition at line 261 of file nvscistream.h.
| NvSciStreamSyncDesc NvSciStreamEvent::syncDesc |
Used with SyncDesc events.
Received by producer and consumer, this contains the description of sync objects which will be used to send fences by the other endpoint(s).
As with sync attributes, components in the stream may modify the description received by the other endpoint.
The recipient owns the memory buffer handles in the event and is responsible for freeing them when no longer needed.
Definition at line 276 of file nvscistream.h.
| NvSciStreamEventType NvSciStreamEvent::type |
Holds the type of event.
