Functions
DW_API_PUBLIC dwStatus	dwImageStreamer_consumerReceive (dwImageHandle_t *image, dwTime_t const timeoutUs, dwImageStreamerHandle_t const streamer)
	Receive a pointer to a dwImageHandle_t from the streamer, acting as a consumer. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_consumerReturn (dwImageHandle_t *image, dwImageStreamerHandle_t const streamer)
	Return the received image back to the producer. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_getCUDAStream (cudaStream_t *stream, dwImageStreamerHandle_t streamer)
	Get CUDA stream used by the image streamer. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_getOutputProperties (dwImageProperties *props, dwImageStreamerHandle_t const streamer)
	Get image properties of the image received from the streamer. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_initialize (dwImageStreamerHandle_t *streamer, const dwImageProperties *from, dwImageType to, dwContextHandle_t ctx)
	Creates and initializes the image streamer capable of moving images between different API types. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_initializeCrossProcess (dwImageStreamerHandle_t *streamer, const dwImageProperties *from, dwImageType to, dwImageStreamerCrossProcessModeParams params, dwContextHandle_t ctx)
	Creates and initializes the image streamer capable of moving images between different API types across processes using NvSciStream. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_initializeCrossProcessEGL (dwImageStreamerHandle_t *streamer, dwImageProperties const *from, dwImageType to, dwImageStreamerCrossProcessModeParams params, dwContextHandle_t ctx)
	Creates a variant of the cross process streamer based on EGL. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_producerReturn (dwImageHandle_t *const image, dwTime_t const timeoutUs, dwImageStreamerHandle_t const streamer)
	The producer streamer waits for the image sent to be returned by the consumer. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_producerSend (dwImageHandle_t image, dwImageStreamerHandle_t const streamer)
	Sends an image through the streamer acting as the producer. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_release (dwImageStreamerHandle_t streamer)
	Releases the image streamer. More...
DW_API_PUBLIC dwStatus	dwImageStreamer_setCUDAStream (cudaStream_t stream, dwImageStreamerHandle_t streamer)
	Sets the CUDA stream for CUDA related streaming operations such as post and receive. More...
