Module ffi 

FFI (Foreign Function Interface) Support

This module handles parsing of FFI manifests and generating the LLVM IR for calling external C functions from Seq code.

FFI is purely a compiler/linker concern - the runtime remains free of external dependencies.

Usage

include ffi:libedit

: repl ( -- )
  "prompt> " readline
  dup string-empty not if
    dup add-history
    process-input
    repl
  else
    drop
  then
;
