SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

C development often suffers from ad-hoc architecture, memory safety gaps, and unclear module boundaries, leading to leaks, undefined behavior, and maintenance pain.

Core Features & Use Cases

  • Modular Architecture: opaque pointers, header encapsulation, and clear layering (domain/infra).
  • Memory Safety & Error Handling: ownership rules, NULL checks, and safe string/buffer practices.
  • Practical Guidance: multi-tenancy considerations and violation checklists for robust C projects.

Quick Start

Apply the C rules in a new or existing project by organizing code into domain/ and infra/ layers, enforce explicit ownership, and implement safe memory patterns.

FAQPage Schema
How do I structure a modular C project to prevent memory leaks and undefined behavior?

Structure a modular C project by organizing code into domain and infra layers, enforcing explicit ownership, and using opaque pointers for header encapsulation to prevent memory leaks and undefined behavior.

What is the best way to enforce memory safety and error handling in procedural C systems?

Enforce memory safety in procedural C systems by applying strict ownership rules, implementing NULL checks, and using standardized error codes alongside safe string and buffer practices.

How does using opaque pointers improve C architecture and module boundaries?

Opaque pointers improve C architecture by enforcing header encapsulation and hiding implementation details, which establishes clear module boundaries and prevents external code from directly accessing internal data structures.

Can I apply these clean architecture rules to existing C codebases with unclear module boundaries?

Yes, you can apply these clean architecture rules to existing C codebases by gradually refactoring code into domain and infra layers, introducing strict ownership, and implementing a violation checklist for compliance.

What are the limitations of using strict ownership and opaque pointers in C development?

Using strict ownership and opaque pointers in C development requires careful pointer management and can introduce slight performance overhead from indirection, but it is necessary to maintain memory safety and prevent undefined behavior.
