Call function in another process
 

Is there a way to make a function available in other processes?

What I need is the following:
A process contains a function that does some calculations on local variables. I want to be able for other processes to call this function and change the variables. Is this possible? If so what is the best way to this?

There are a few mechanisms for this sort of thing. Have a read about dbus and see if it suits your needs. See: http://www.freedesktop.org/wiki/Software/dbus
