proxies in IPC

Hi,

Does QNX 6.0 offer the method of proxies in IPC? Since I check the manual, I
cann’t find it. So, I am wondering whether the method is used for QNX 4.0,
not for QNX6.0

Thanks,

Belinda

Correct, the construct for doing this under QNX6 is called a Pulse.

No, there are no proxies. There are pulses, which are the non-blocking
form of notification IPC. If you’re migrating from QNX4 to QNX6, you
may want to take a look at the migration toolkit, it has docs on what
has changed, and how you might want/need to restructure your code.

But the pulse in QNX6 can not work over the net

Pulse (and signal) could cross QNET for a while now (starting
from 6.1 I think?).

??? The doc of both 6.1 and 6.2 for MsgSendPulse says you can’t
use MsgSendPulse to send pulses across the network
