# Peta::FFI

Peta::FFI — Dynamic FFI for calling C library functions from Perl

Three layers:
- Layer 0: Raw FFI via `dlopen()` + `call()` — user provides type signatures
- Layer 1: Pre-baked bindings — `Peta::FFI::Libc`, `Peta::FFI::UUID`
- Layer 2: Discovery — `scan()` enumerates available libraries and functions

Uses libffi for the raw call dispatch — any C function signature works.
