DESCRIPTION:
Ruby-FFI is a ruby extension for programmatically loading dynamic libraries, binding functions within them, and calling those functions from Ruby code. Moreover, a Ruby-FFI extension works without changes on Ruby and JRuby. Discover why should you write your next extension using Ruby-FFI here.
FEATURES/PROBLEMS:
It has a very intuitive DSL
It supports all C native types
It supports C structs (also nested), enums and global variables
It supports callbacks
It has smart methods to handle memory management of pointers and structs
SYNOPSIS:
require 'ffi' module MyLib extend FFI::Library attach_function :puts, [ :string ], :int end MyLib.puts 'Hello boys using libc!'
