Description
You can use the sk_setChannelHandler() function to organize the flow of messages for your application. Once a channel has been assigned to an application, the sk_setChannelHandler() function causes the specified handler function to be called whenever a CSP-initiated message arrives on a span and channel. This function does not affect the routing of any acknowledgment messages.
