Procedure for stream detection

The "Request for connecting a new stream" process is run when a request for incoming stream connection is detected.
This process is run only if:
  • ..Detection applied to the stream is set to True.
  • the "Detection of incoming streams" option was checked in the description window of the streams.
Note: This process is run in a specific thread of WLanguage. Therefore, it is subject to limitations specific to the threads. See Managing the threads for more details.
