The timeout value can have the following values:</p> -<ul> -<li>when <em>millisec</em> is 0, the function returns instantly.</li> -<li>when <em>millisec</em> is set to <b>osWaitForever</b> the function will wait for an infinite time until a specified signal is set.</li> -<li>all other values specify a time in millisecond for a timeout.</li> -</ul> -<p><b><a class="el" href="group___c_m_s_i_s___r_t_o_s___status.html">Status and Error Codes</a></b><br/> -</p> -<ul> -<li><em>osOK:</em> no signal received when the timeout value <em>millisec</em> was 0.</li> -<li><em>osEventTimeout:</em> signal not occurred within timeout</li> -<li><em>osEventSignal:</em> signal occurred, <em>value.signals</em> contains the signal flags; these signal flags are cleared.</li> -<li><em>osErrorValue:</em> the value <em>signals</em> is outside of the permitted range.</li> -<li><em>osErrorISR:</em> <a class="el" href="group___c_m_s_i_s___r_t_o_s___signal_mgmt.html#ga38860acda96df47da6923348d96fc4c9">osSignalWait</a> cannot be called from interrupt service routines.</li> -</ul> -<dl class="section note"><dt>Note</dt><dd>Cannot be called from <a class="el" href="_function_overview.html#CMSIS_RTOS_ISR_Calls">Interrupt Service Routines</a>.</dd></dl> -<p><b>Code Example</b> </p> -<div class="fragment"><div class="line"><span class="keywordtype">void</span> Thread_2 (<span class="keywordtype">void</span> <span class="keyword">const</span> *arg);</div> -<div class="line"> </div> -<div class="line"><a class="code" href="group___c_m_s_i_s___r_t_o_s___thread_mgmt.html#gaee93d929beb350f16e5cc7fa602e229f" title="Create a Thread Definition with function, priority, and stack requirements.">osThreadDef</a> (Thread_2, <a class="code" href="group___c_m_s_i_s___r_t_o_s___thread_mgmt.html#ga7f2b42f1983b9107775ec2a1c69a849aa914433934143a9ba767e59577c56e6c2" title="priority: high">osPriorityHigh</a>, 1, 0);</div> -<div class="line"> </div> -<div class="line"><span class="keyword">static</span> <span class="keywordtype">void</span> EX_Signal_1 (<span class="keywordtype">void</span>) {</div> -<div class="line"> <a class="code" href="cmsis__os_8h.html#adfeb153a84a81309e2d958268197617f" title="Thread ID identifies the thread (pointer to a thread control block).">osThreadId</a> thread_id;</div> -<div class="line"> <a class="code" href="group___c_m_s_i_s___r_t_o_s___definitions.html#structos_event" title="Event structure contains detailed information about an event.">osEvent</a> evt;</div> -<div class="line"> </div> -<div class="line"> thread_id = <a class="code" href="group___c_m_s_i_s___r_t_o_s___thread_mgmt.html#gac59b5713cb083702dce759c73fd90dff" title="Create a thread and add it to Active Threads and set it to state READY.">osThreadCreate</a> (<a class="code" href="group___c_m_s_i_s___r_t_o_s___thread_mgmt.html#gaf0c7c6b5e09f8be198312144b5c9e453" title="Access a Thread definition.">osThread</a>(Thread_2), NULL);</div> -<div class="line"> <span class="keywordflow">if</span> (thread_id == NULL) {</div> -<div class="line"> <span class="comment">// Failed to create a thread.</span></div> -<div class="line"> }</div> -<div class="line"> <span class="keywordflow">else</span> {</div> -<div class="line"> :</div> -<div class="line"> <span class="comment">// wait for a signal</span></div> -<div class="line"> evt = <a class="code" href="group___c_m_s_i_s___r_t_o_s___signal_mgmt.html#ga38860acda96df47da6923348d96fc4c9" title="Wait for one or more Signal Flags to become signaled for the current RUNNING thread.">osSignalWait</a> (0x01, 100);</div> -<div class="line"> <span class="keywordflow">if</span> (evt.<a class="code" href="group___c_m_s_i_s___r_t_o_s___definitions.html#ad477a289f1f03ac45407b64268d707d3" title="status code: event or error information">status</a> == <a class="code" href="group___c_m_s_i_s___r_t_o_s___status.html#gae2e091fefc4c767117727bd5aba4d99ea5df7e9643aa8a2f5f3a6f6ec59758518" title="function completed; signal event occurred.">osEventSignal</a>) {</div> -<div class="line"> <span class="comment">// handle event status</span></div> -<div class="line"> }</div> -<div class="line"> }</div> -<div class="line">}</div> -</div><!-- fragment --> -</div> -</div> -</div><!-- contents --> -</div><!-- doc-content --> -<!-- start footer part --> -<div id="nav-path" class="navpath"><!-- id is needed for treeview function! --> - <ul> - <li class="footer">Generated on Tue Oct 27 2015 14:35:43 for CMSIS-RTOS by ARM Ltd.
