C Standard Library
The C standard library is a C11 standard library implemented by:
-
libc: provides thread-related functions and a majority of standard functions.
-
libm: provides basic mathematical functions.
-
libdl: provides functions related to dynamic linking, such as dlopen.
Version
1.2.0
Capabilities
C 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.

libc++
libc++ is an implementation of the C++ standard library.
Version
10.0.1
Capabilities
The C++11 and C++14 standards are supported, and the C++17 and C++20 standards are on the way.
OpenSL ES
OpenGL ES is an embedded, cross-platform audio processing library.
Capabilities
OpenSL ES Interfaces Supported by Native APIs
zlib
zlib is a general data compression library implemented in C/C++.
EGL
EGL is an interface between Khronos rendering APIs (such as OpenGL ES and OpenVG) and the underlying native window system. OpenHarmony supports EGL.
