Can you elaborate?
Are you discussing API calls? Remote Procedure Calls?
My initial assumption was you wanted info on Data Marshaling — utilizing the likes of JSON or XML to communicate data between different programs.
But then maybe you mean data allocation in memory, how the heap and stack work, etc.? References and pointers, and deep and shallow copies, etc.?
No sympathy for either except civilians caught in between.
The best thing in this is that Russia may receive less drones from Iran used to bombard Ukraine, so that makes me happy
