Hi there, If I want to send my own event or message to notify my other part of the system when a certain condition is met, how do I implement that in C++ code? For example, I might want to do data analysis of the RTP packets in C++, and when I detected the right timing where I want to play an audio, I can send an event to my other part of the system to play an audio file. Is there any hint or sample code that I can take a look? Thanks, Frankie
