<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>Function calls from interrupt service routines</b></p>
<p>The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):</p>
<ul>
<li><a class="el" href="group___c_m_s_i_s___r_t_o_s___signal_mgmt.html#ga3de2730654589d6c3559c4b9e2825553">osSignalSet</a></li>

</ul>
<p>Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called from an ISR context the status code <b>osErrorISR</b>. In some implementations this condition might be caught using the HARD FAULT vector.</p>
<p>Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time. If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code <b>osErrorISRRecursive</b>.</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>
