welcome to the list! > I was looking at the Hello program and the RPC mechanism. as i > understood RPC does not support passing pointer as parameter > how i can pass a parameter by reference where i need to change its value > in the server side. you can find a detailed description of the RPC mechanism in Section 8.12. "Remote procedure calls" of the manual [1]. In short, you have two options: 1. Define a POD struct used as return type of your RPC functiion. For an example, take a look that the Framebuffer::Session::mode RPC function [2]. 2. You can pass a reference to a POD object as RPC argument. This is rarely used but you can find find an example in the Raspberry-Pi-specific platform-session interface, namely the setup_framebuffer RPC function [3].
