A question about sys_msg.h

Hello.

I have a question regarding some programming of processes that one could
do under QNX4, since I would like to know how it is done under QRTP.
Under QNX4, there was a means, using the system message definitions in
sys/sys_msg.h, to make a process respond to a sin ver and also to
respond appropriately to system death messages. I was wondering if this
functionality has been continued with QRTP or if it is accomplished
another way. If this functionality has not been brought over, then it
will affect whether we will be use the message structures analogous to
the QNX4 _sysmsg_hdr in our messages.

Thanks alot.

There is no system messages of this sort.

There is a way to be informed of process death but it ain;t simple.
It’s been discussed in a thread a while ago.


Thanks alot.
