SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enables developers to integrate Cangjie code with existing C libraries and systems, allowing for efficient interoperability and leveraging the strengths of both languages.

Core Features & Use Cases

  • Foreign Function Interface (FFI): Declare and call C functions directly from Cangjie.
  • Type Mapping: Supports mapping of fundamental C types, structs, pointers, and arrays to Cangjie equivalents.
  • Memory Management: Provides tools for safe memory allocation and deallocation when interacting with C.
  • Callback Handling: Enables C code to call back into Cangjie functions.
  • Use Case: Integrate a high-performance C-based image processing library into your Cangjie application for faster image manipulation.

Quick Start

Use the cangjie-ffi skill to declare a C function named add that takes two integers and returns their sum, then call it from Cangjie.
