How can we simulate receiving the RSSL_STREAM_UNSPECIFIED message? What should the client application behavior be when receiving that message? From this post, https://community.developers.refinitiv.com/questions/46630/rssl-state-message-and-how-do-we-handle-rssl-strea.html, it seems that the correct response is to ignore/not process RSSL_STREAM_UNSPECIFIED. Are there any cases where RSSL_STREAM_UNSPECIFIED should be processed or acted on?
Not tried this but I expect you could modify one of the Provider examples (not NIProvider) that are supplied in the ETA subfolder to encode a message in the desired format and publish it.
You could then connect your Consumer directly to your provider and consume it.
