Libev is a high-performance event loop/event model with lots of features.
It is modelled (very loosely) after libevent and the Event perl module,
but aims to be faster and more correct, and also more featureful. And
also smaller.
libevdev is a wrapper library for evdev devices. It moves the common
tasks when dealing with evdev devices into a library and provides a
library interface to the callers, thus avoiding erroneous ioctls, etc.
The eventual goal is that libevdev wraps all ioctls available to evdev
devices, thus making direct access unnecessary.

This is a quick-n-dirty BSD licensed clone of backtrace facility found
in the GNU libc, mainly intended for porting Linuxish code to BSD
platforms, however it can be used at any platform which has a gcc
compiler.
A library which may be used to explain Unix and Linux system call
errors. The library is not quite a drop-in replacement for strerror, but
it comes close. Each system call has a dedicated libexplain function.
Protocol Buffers are a way of encoding structured data in an efficient yet
extensible format. Google uses Protocol Buffers for almost all of its
internal RPC protocols and file formats.
PWLib is a multi-platform code library that can be used to write
applications that will compile and run on the BSD Unixes, Windows, Linux
and a few other Unix variants. It was developed by Equivalence Ltd Pty.
It is used by the OPAL library.
