Lua C Integration

Introduction

Lua's C API enables seamless integration with C code, allowing developers to extend Lua with high-performance native functionality or embed Lua as a scripting engine within C applications. This bidirectional integration makes Lua ideal for performance-critical applications requiring scripting capabilities.

The C API operates through a virtual stack for passing values between Lua and C, with functions for manipulating Lua values, calling functions, and managing memory. Understanding stack operations and Lua's data model is essential for safe, efficient C integration.

This skill covers the Lua stack, calling C from Lua, calling Lua from C, creating C modules, userdata and metatables, error handling, memory management, and performance optimization patterns.
