SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies the complex task of integrating Zig code with existing C libraries and vice-versa, enabling efficient development in mixed-language projects.

Core Features & Use Cases

  • C API Integration: Use @cImport and @cInclude to call C functions and use C types directly within Zig.
  • Zig Export to C: Expose Zig functions and data structures for consumption by C code.
  • ABI Compatibility: Define extern struct and packed struct to precisely match C memory layouts.
  • Header Translation: Utilize translate-c to understand how Zig interprets C headers, akin to bindgen.
  • Mixed Builds: Facilitate building projects that combine both C and Zig source files using build.zig.

Quick Start

Use the zig-cinterop skill to call the C function my_c_function from your Zig code.

FAQPage Schema
How do I call C functions from Zig?▼

You can call C functions from Zig by using the built-in @cImport and @cInclude directives to import C headers and access the functions directly within your Zig code.

What is the best way to ensure ABI compatibility when defining C-compatible data structures in Zig?▼

To ensure ABI compatibility, define your data structures in Zig using extern struct or packed struct, which precisely match C memory layouts for seamless interoperability.

Can I export Zig functions for consumption by C code?▼

Yes, you can export Zig functions and data structures for C consumption, allowing existing C codebases to seamlessly call and utilize your compiled Zig logic.

How do I build a mixed C and Zig project?▼

You can build mixed C and Zig projects by configuring your build.zig file to compile and link both C and Zig source files together into a single executable or library.

Does Zig have a tool similar to bindgen for header translation?▼

Yes, Zig includes the translate-c utility to understand how Zig interprets C headers, providing functionality akin to bindgen for ensuring ABI compliance.
