Is there a way I can use a variable in the shared memory space, monitor the memory address with gtk looking for a change of state and cause a signal to be emitted?I'm not sure if this is the best and or only way to do it but I just have a timeout that runs at a certain rate (10 Hz in my case) and looks at the value of the variable in memory, if the value changes then it goes in and does whatever processing it needs to do.
Maybe you should use signals [signal(2)] to inform the process, this
way it can be done without polling.
