 124 <ul>
 125 <li>File interface for reading and writing files.</li>
 126 <li>I/O interface for standard I/O stream retargeting (stderr, stdin, stdout).</li>

 132 Overview of CMSIS-Compiler</div></div>
 133     <p>Standard C library functions are platform independent, but the implementations of the low-level I/O and multithreading support are tailored to the target compiler toolchains.</p>
 134 <h1><a class="anchor" id="autotoc_md0"></a>
 135 Access to CMSIS-Compiler</h1>
 136 <p>CMSIS-Compiler is maintained in a GitHub repository and is also released as a standalone package in CMSIS Pack format.</p>
 137 <ul>
 138 <li><a href="https://github.com/Arm-Software/CMSIS-Compiler"><b>CMSIS-Compiler GitHub Repo</b></a> provides the full source code of CMSIS-Compiler components.</li>
 139 <li><a href="https://arm-software.github.io/CMSIS-Compiler/latest/"><b>CMSIS-Compiler Documentation</b></a> explains how to use the library and describes the implemented functions in details.</li>

 143 Key Features and Benefits</h1>
 144 <ul>
 145 <li>CMSIS-Compiler allows individual retargeting configuration for common I/O interfaces: file, stderr, stdin, stdout.</li>
 146 <li>Implements several ready-to-use retarget variants: into File, Breakpoint, Event Recorder, ITM, as well as user-specific variant.</li>
 147 <li>Supports common standard C libraries, such as from Arm Compiler and GCC (Newlib) toolchains. IAR support is planned.</li>
 148 <li>Provides implementation templates and examples to get started. </li>
