## C Standard Library



C11 standard library implemented by [libc, libm, and libdl](https://en.cppreference.com/w/c/header).

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.

**Capabilities**

The C++11 and C++14 standards are supported, and the C++17 and C++20 standards are on the way.

## OpenSL ES
