event call on writing a buffer?

[drkhodakarami]

Hi
Is there an option to add a method to be called as event on second inter process when the inter process one is writing a buffer? in other words, how to continuously listen to the buffer and find when to read it?
watch this video for an example of what i have in mind, take note, the second application does not know when the message is being sent and will be notified by an event
