Hello everyone, 

I would like to know if QNX supports any asynchronous IPC or not. I found that there is an experimental feature, "
Asynchronous messaging", on the website.  I wanted to see how it works but I could not compile the code because there is
 no sys/asyncmsg.h file. Any suggestions on that? 

Thank you very much, 
Best Regards

Re: Asynchronous IPC

QNX supports pulses, sockets, pipes and POSIX message queues for
asynchronous IPC. The async message mechanism was abandoned (for good
reasons).

Re: Asynchronous IPC

Thanks Elad for the information. What is the ideal asynchronous IPC mechanism for communication huge chunk of data from 
one process to another? I see that with mqueue one can transfer 1024*4086 bytes, but is it also possible with pulse as 
well?
