C (C99/C11/C17) Reference

The C programming language provides a low-level, high-performance toolkit for systems programming. It is widely used in the Dev-Centr ecosystem for firmware, drivers, and performance-critical core libraries.

In Dev-Centr, we strongly endorse Literate Programming (LP) for all C development. The historically opaque and verbose nature of C makes it the perfect candidate for an inverted documentation-first approach.

Core Principles for C in Dev-Centr

  1. Literate First: Build your C modules as CentrMark (.cmk) or Markdown/Tangle documents. Explain the architecture before the implementation.

  2. Explicit Constraints: Use const, restrict, and static wherever applicable to help the compiler and AI agents understand pointer aliasing and visibility.

  3. Memory Safety Patterns: Use established Dev-Centr patterns for safe memory allocation and bounds checking, even in standard C.

  • Native (CentrMark): Use ::: tangle [file="main.c"] blocks for a unified AST-based development experience.

  • CWEB / noweb: Use these for traditional batch-processed LP if you require extreme portability.

  • Entangled: Use Markdown-based LP with real-time syncing if you prefer a standard source-file-first IDE workflow but want synchronous documentation.
