Restrictions

  • If this API is not called, no timeout occurs by default. If this API is called for multiple times in a process, the last configured interval is used.
  • You can call this API to set the timeout interval after acl.init is called for initialization in a process. Tasks delivered by calling acl.rt.stream_wait_event in the process can wait within the configured timeout interval.

    The acl.rt.stream_wait_event API is asynchronous. Successful API calling only indicates that the task is successfully delivered but not executed. Therefore, if the wait time exceeds the configured timeout interval, an error is reported after the acl.rt.synchronize_stream API is called.
