Loosing signal while reading bus systems under C

[Victor Andres]

It would be an option, reduce the rate of writing the signals in the bus, 
but this would limit the functionality of my application. I'm doing the 
processing of signal (sensors datas) incoming from serial port, to transfer 
them to multiple processes and applications. If I reduce the dbus signal 
rate, I will reduce the performance of my hardware.

I think I have to use another means of IPC. I liked d-bus for the 
possibility that a transmitter sending datas (signals) to a channel, and one 
o various processes read and atiend on it (without these process have to be 
constantly referring to an address).

Regards,
Víctor Andrés

How about queuing  your messages in the transmitting process, then
empty the queue in a single burst (over DBUS itself) at a lesser
frequency? Would this work for your app or does it need the messages
as soon as they are generated?

If you have a fixed requirement of sending 1200/sec then you might
have to look at other means of IPC...shared mem, fifo/ipes.
