cuda::experimental::stf::unregister_stream#

inline void cuda::experimental::stf::unregister_stream(
async_resources_handle &async_resources,
decorated_stream &dstream,
)#

Unregisters a decorated CUDA stream from asynchronous resources.

Performs cleanup operations to release resources associated with a previously registered stream. This includes:

  • Releasing the unique ID back to the resource manager

  • Invalidating the decorated stream’s internal ID

Note

Should be paired with register_stream() for proper resource management

Parameters:

  • async_resources – [inout] Handle to asynchronous resources manager

  • dstream – [inout] Decorated stream to unregister. Its id will be set to -1.

Pre:

dstream.id must be valid (≥ 0) before calling this function

Post:

dstream.id == -1 and associated resources are released
