1# Native Standard Libraries Supported by OpenHarmony 2 3## Overview 4 5**Table 1** Standard libraries supported by OpenHarmony 6 7| Library | Description | 8| :-------- | :----------------------------------------------------------- | 9| C standard library | C11 standard library implemented by [libc, libm, and libdl](https://en.cppreference.com/w/c/header). | 10| C++ standard library ([libc++](https://libcxx.llvm.org/))| An implementation of the C++ standard library. | 11| Open Sound Library for Embedded Systems ([OpenSL ES](https://www.khronos.org/registry/OpenSL-ES/))| An embedded, cross-platform audio processing library.| 12| [zlib](https://zlib.net/) | A general data compression library implemented in C/C++.| 13| [EGL](https://www.khronos.org/egl/) | A standard software interface between rendering APIs and the underlying native window system.| 14| Open Graphics Library for Embedded Systems ([OpenGL ES](https://www.khronos.org/opengles/))| A cross-platform software interface for rendering 3D graphics on embedded and mobile systems.| 15 16## C Standard Library 17 18The C standard library is a C11 standard library implemented by: 19 20libc: provides thread-related functions and a majority of standard functions. 21 22libm: provides basic mathematical functions. 23 24libdl: provides functions related to dynamic linking, such as **dlopen**. 25 26**Version** 27 281.2.0 29 30**Capabilities** 31 32C standard library includes a set of header files in accordance with standard C and provides common functions, such as the functions related to input/output (I/O) and string control. 33 34**<font size=5>musl</font>** 35 36[Native API Symbols Not Exported](musl-peculiar-symbol.md) 37 38## libc++ 39 40[libc++](https://libcxx.llvm.org/) is an implementation of the C++ standard library. 41 42**Version** 43 4410.0.1 45 46**Capabilities** 47 48The C++11 and C++14 standards are supported, and the C++17 and C++20 standards are on the way. 49 50## OpenSL ES 51 52[OpenSL ES](https://www.khronos.org/registry/OpenSL-ES/) is an embedded, cross-platform audio processing library. 53 54## zlib 55 56[zlib](https://zlib.net/) is a general data compression library implemented in C/C++. 57 58## EGL 59 60EGL is an interface between Khronos rendering APIs (such as OpenGL ES and OpenVG) and the underlying native window system. OpenHarmony supports EGL. 61 62**Symbols Exported from the Standard Library** 63 64[EGL Symbols Exported from Native APIs](../third_party_opengl/egl-symbol.md) 65 66## OpenGL ES 67 68OpenGL is a cross-platform software interface for 3D graphics processing. [OpenGL ES](https://www.khronos.org/opengles/) is a OpenGL specification for embedded devices. OpenHarmony supports OpenGL ES 3.0. 69 70**Capabilities** 71 72OpenGL ES 3.0 73 74**Symbols Exported from the Standard Library** 75 76[OpenGL ES 3.0 Symbols Exported from Native APIs](../third_party_opengl/openglesv3-symbol.md) 77
