Hello, 

I want to see what QNX constructs I can use for following two purposes. 

1. I want to broadcast an Event, X, to all processes. It should not matter in what state the process is. Each process 
must give highest priority to this Event X, and call its event handler onEventX(). Its like software interrupt. 

2. This Event handler will do some processing  and send the Response /Ack to original process , Y. the original main 
process M, will collect all the responses, when it has responses from all the processes, then it will reset entire 
system. 

how can I do above two tasks in QNX ?

thanks
