libuv is a multi-platform support library with a focus on asynchronous I/O. Among other things, it supports event loops via epoll, kqueue, and similar IOCP, and event ports, asynchronous TCP/UDP sockets, asynchronous DNS resolution, asynchronous file system operations, and threading primitives.

The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. Furthermore, libevent also support callbacks due to signals or regular timeouts.

libevent is meant to replace the event loop found in event driven network servers. An application just needs to call event_dispatch() and then add or remove events dynamically without having to change the event loop.

libev provides a full-featured and high-performance event loop that is loosely modelled after libevent. It includes relative timers, absolute timers with customized rescheduling, synchronous signals, process status change events, event watchers dealing with the event loop itself, file watchers, and limited support for fork events.

GNU Libffcall is a collection of libraries that can be used to build foreign function call interfaces in embedded interpreters.

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.

The libffi library provides a portable, high level programming interface to various calling conventions. This allows a programmer to call any function specified by a call interface description at run-time.

FFI stands for Foreign Function Interface. A foreign function interface is the popular name for the interface that allows code written in one language to call code written in another language. The libffi library really only provides the lowest, machine dependent layer of a fully featured foreign function interface. A layer must exist above libffi that handles type conversions for values passed between the two languages.

libFTDI is a library to talk to FTDI chips: FT232BM, FT245BM, FT2232C, FT2232D, FT245R and FT232H including the popular bitbangmode. To use libftdi without root privileges it is necessary to install the necessary udev rules. This can be done by extending udev-service-type in the operating-system configuration file with this package, as in:

(udev-rules-service 'libftdi libftdi #:groups '("plugdev")

Additionally, the plugdev group should be registered in the supplementary-groups field of your user-account declaration. Refer to info "(guix) Base Services" for examples.

libidn is a library implementing of the Stringprep, Punycode and IDNA specifications. These are used to encode and decode internationalized domain names according to the IDNA2003 specifications. It includes native C, C# and Java libraries.

Libidn2 is an internationalized domain library implementing the IDNA2008 specifications. Libidn2 is believed to be a complete IDNA2008 implementation, but has yet to be as extensively used as the original Libidn library.
