This is a legacy project, do not use it for new projects. Ruby 2.3 and later should make this obsolete. kgio provides non-blocking I/O methods for Ruby without raising exceptions on EAGAIN and EINPROGRESS.
Can avoid expensive exceptions on common EAGAIN/EINPROGRESS errors, returning :wait_readable or :wait_writable instead. These exceptions got more expensive to hit under Ruby 1.9.2 (but were fixed in Ruby 1.9.3 and later to 1.9.1 performance levels, which were still bad)
Returns the unwritten portion of the string on partial writes, making it ideal for buffering unwritten data.
May call any method defined to be "kgio_wait_writable" or "kgio_wait_readable" methods to allow socket/pipe objects to make custom callbacks (such as adding the file descriptor to a poll set and yielding the current Fiber).
Uses accept4 on newer GNU/Linux systems to avoid unnecessary fcntl() calls
Uses MSG_DONTWAIT on GNU/Linux to further avoid unnecessary fcntl() calls
Compatible with existing Ruby IO objects and Ruby threading.
The library consists of a C extension so you'll need a Unix-like system with a C compiler and Ruby development libraries/headers. You may install it via RubyGems.org:
gem install kgio
