Wrapper Description of C library
wrap_yaml LibYAML is a YAML parser and emitter library.
wrap_sdl Simple DirectMedia Layer is a cross-platform development library designed to provide low-level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award-winning catalog and many Humble Bundle games.
wrap_libusb libusb is a C library that provides generic access to USB devices. It is intended to be used by developers to facilitate the production of applications that communicate with USB hardware. It is portable: Using a single cross-platform API, it provides access to USB devices on Linux, macOS, Windows, etc.
wrap_quirc Quirc is a C library for scanning QR codes.
wrap_lz4 Extremely fast compression library.
wrap_libqrencode Libqrencode is a fast and compact library for encoding data in a QR Code, a 2D symbology that can be scanned by handy terminals such as a smartphone. The capacity of QR Code is up to 7000 digits or 4000 characters and has high robustness.
wrap_libgit2 libgit2 is a portable, pure C implementation of the Git core methods provided as a re-entrant linkable library with a solid API, allowing you to write native speed custom Git applications in any language which supports C bindings.
wrap_gsl The GNU Scientific Library (GSL) is a collection of routines for numerical computing.
