<div class="contents">
<div class="textblock"><p>The file <b><a class="el" href="cmsis__os_8h.html">cmsis_os.h</a></b> is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS). Each RTOS that is compliant with CMSIS-RTOS shall provide a specific <b><a class="el" href="cmsis__os_8h.html">cmsis_os.h</a></b> header file that represents its implementation.</p>
<p>The file <a class="el" href="cmsis__os_8h.html">cmsis_os.h</a> contains:</p>
<ul>
<li>CMSIS-RTOS API function definitions</li>
<li>struct definitions for parameters and return types</li>
<li>status and priority values used by CMSIS-RTOS API functions</li>
<li>macros for defining threads and other kernel objects</li>
</ul>
<p><b>Name conventions and header file modifications</b></p>
<p>All definitions are prefixed with <b>os</b> to give an unique name space for CMSIS-RTOS functions. Definitions that are prefixed <b>os_</b> are not used in the application code but local to this header file. All definitions and functions that belong to a module are grouped and have a common prefix, i.e. <b>osThread</b>.</p>
<p>Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation. These definitions can be specific to the underlying RTOS kernel.</p>
<p>Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.</p>
<p><b>Define and reference object definitions</b></p>
<p>With <b>#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file that is used throughout a project as shown below:</p>
