1b877906bSopenharmony_ci# Introduction {#mainpage} 2b877906bSopenharmony_ci 3b877906bSopenharmony_ciGLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and 4b877906bSopenharmony_ciVulkan application development. It provides a simple, platform-independent API 5b877906bSopenharmony_cifor creating windows, contexts and surfaces, reading input, handling events, etc. 6b877906bSopenharmony_ci 7b877906bSopenharmony_ci@ref news list new features, caveats and deprecations. 8b877906bSopenharmony_ci 9b877906bSopenharmony_ci@ref quick_guide is a guide for users new to GLFW. It takes you through how to 10b877906bSopenharmony_ciwrite a small but complete program. 11b877906bSopenharmony_ci 12b877906bSopenharmony_ciThere are guides for each section of the API: 13b877906bSopenharmony_ci 14b877906bSopenharmony_ci - @ref intro_guide – initialization, error handling and high-level design 15b877906bSopenharmony_ci - @ref window_guide – creating and working with windows and framebuffers 16b877906bSopenharmony_ci - @ref context_guide – working with OpenGL and OpenGL ES contexts 17b877906bSopenharmony_ci - @ref vulkan_guide - working with Vulkan objects and extensions 18b877906bSopenharmony_ci - @ref monitor_guide – enumerating and working with monitors and video modes 19b877906bSopenharmony_ci - @ref input_guide – receiving events, polling and processing input 20b877906bSopenharmony_ci 21b877906bSopenharmony_ciOnce you have written a program, see @ref compile_guide and @ref build_guide. 22b877906bSopenharmony_ci 23b877906bSopenharmony_ciThe [reference documentation](modules.html) provides more detailed information 24b877906bSopenharmony_ciabout specific functions. 25b877906bSopenharmony_ci 26b877906bSopenharmony_ci@ref moving_guide explains what has changed and how to update existing code to 27b877906bSopenharmony_ciuse the new API. 28b877906bSopenharmony_ci 29b877906bSopenharmony_ciThere is a section on @ref guarantees_limitations for pointer lifetimes, 30b877906bSopenharmony_cireentrancy, thread safety, event order and backward and forward compatibility. 31b877906bSopenharmony_ci 32b877906bSopenharmony_ciFinally, @ref compat_guide explains what APIs, standards and protocols GLFW uses 33b877906bSopenharmony_ciand what happens when they are not present on a given machine. 34b877906bSopenharmony_ci 35b877906bSopenharmony_ciThis documentation was generated with Doxygen.
