Function Documentation

LIBED247_EXPORT ed247_status_t ed247_wait_frame	(	ed247_context_t	context,
		ed247_stream_list_t *	streams,
		int32_t	timeout_us
	)

Blocks until a frame is received and processed, and at least a stream has available data.

If several frames has been received since last wait_frame/wait_during, all of them are processed.
streams, if not NULL, will be set to the list of streams with incomming data available. its lifespan is the same as the context, but you can safely call ed247_stream_list_free().

Parameters

[in]	context	Context identifier
[out]	streams	List of streams that received samples, can be NULL
[in]	timeout_us	Timeout value, in microseconds

Return values

ED247_STATUS_SUCCESS
ED247_STATUS_FAILURE
ED247_STATUS_TIMEOUT

LIBED247_EXPORT ed247_status_t ed247_wait_during	(	ed247_context_t	context,

	)

Blocks until duration is elapsed. Processing all received frames.

streams, if not NULL, will be set to the list of streams with incomming data available. its lifespan is the same as the context, but you can safely call ed247_stream_list_free().

Parameters
