ConcatOutput property

Pointer<NativeFunction<OrtStatusPtr Function(Pointer<OrtLoopKernelHelper> this_ptr, Pointer<Void> stream_handle, Pointer<Pointer<OrtValue>> per_iteration_outputs, Size num_per_iteration_outputs, Pointer<Void> output, Size output_size_in_bytes)>> ConcatOutput

\brief Helper function that concatenates OrtValue instances from each loop iteration into a single pre-allocated output buffer.

\note Implementing this function is required for all Loop opset versions.

\paramin this_ptr The OrtLoopKernelHelper instance. \paramin stream_handle Optional native stream handle that enables asynchronous operations. May be NULL. \paramin per_iteration_outputs Array of OrtValue instances from each iteration. All OrtValue elements have the same shape. \paramin num_per_iteration_outputs The number of OrtValue* elements in the per_iteration_outputs array. \paramout output The pre-allocated output buffer. Memory is allocated on the device for the EP running the Loop node. \paramin output_size_in_bytes The size in bytes of the output buffer. It is guaranteed to be large enough to hold the concatenated data of each element in per_iteration_outputs.
