Zig from Common Lisp: CFFI Definitions, Dynamic Libraries, Opaque Handles, and Callbacks

A practical two-hour session on Zig from Common Lisp, focused on CFFI Definitions, Dynamic Libraries, Opaque Handles, and Callbacks. The session treats Zig as a native component exposed through C-compatible boundaries, with attention to exported symbols, allocators, packaging, host-runtime tests, and failure handling.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Zig from Common Lisp
• Apply CFFI Definitions in a small working example
• Apply Dynamic Libraries in a small working example
• Apply Opaque Handles in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
