D-Bus Tutorial

Intorduction

In this repository, we test D-Bus by providing clear examples of how to implement both a client and a server in two popular programming languages: C and Python. D-Bus is a powerful inter-process communication protocol that is widely used in Linux for software components to communicate with each other.

Project Goals

Our overarching aim is to delve deep into the D-Bus communication protocol and harness its capabilities for inter-process communication. By embarking on this project, we're not only setting out to understand D-Bus in theory but also to practically implement and test it across different programming languages, namely C and Python.

To be more specific, our objectives are:

  • Understanding D-Bus: Gain a comprehensive understanding of the D-Bus communication protocol.
  • Cross-Language Implementation: Develop both client and server programs using C and Python, showcasing the flexibility and applicability of D-Bus across languages.
  • Seamless Communication: Implement and test communication between the client and server, ensuring seamless data exchange through method calls and return values.
  • Error Handling Mastery: Familiarize ourselves with error handling in D-Bus, preparing for any potential pitfalls or exceptions that may arise.
  • Evaluating Interoperability: Evaluate the characteristics, advantages, and challenges of D-Bus communication between different languages.
  • Broadening Networking Knowledge: Ultimately, elevate our knowledge in communication protocols and networking as a whole through hands-on experience.

Usages

To run the code, ensure you have the required libraries and dependencies installed.

Follow the setting README.
