This module allows Ruby programs to access their OS’s native sendfile(2) system call from any IO object. Your kernel must export a recognized signature for the sendfile(2) system call to use this module. Currently, that includes Linux, Solaris and FreeBSD.
Download and install the latest package from the rubyforge.org RubyGems repository.
$ gem install sendfile
If the tests all pass, you’re ready to start using sendfile!
Here’s a small example of a use of IO#sendfile.
require 'socket'
require 'rubygems'
require 'sendfile'
s = TCPSocket.new 'yourdomain.com', 5000
File.open 'somefile.txt' { |f| s.sendfile f }
s.closeSee the test scripts for more examples on how to use this module.
