| <p>Callouts are Apache Mynewt OS timers.</p> |
| <div class="section" id="description"> |
| <h2>Description<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2> |
| <p>Callout is a way of setting up an OS timer. When the timer fires, it is |
| delivered as an event to task’s event queue.</p> |
| <p>User would initialize their callout structure using |
| <a class="reference internal" href="#c.os_callout_init" title="os_callout_init"><code class="xref c c-func docutils literal notranslate"><span class="pre">os_callout_init()</span></code></a>, or <code class="xref c c-func docutils literal notranslate"><span class="pre">os_callout_func_init()</span></code> and |
| then arm it with <a class="reference internal" href="#c.os_callout_reset" title="os_callout_reset"><code class="xref c c-func docutils literal notranslate"><span class="pre">os_callout_reset()</span></code></a>.</p> |
| <p>If user wants to cancel the timer before it expires, they can either use |
| <a class="reference internal" href="#c.os_callout_reset" title="os_callout_reset"><code class="xref c c-func docutils literal notranslate"><span class="pre">os_callout_reset()</span></code></a> to arm it for later expiry, or stop it altogether |
| by calling <a class="reference internal" href="#c.os_callout_stop" title="os_callout_stop"><code class="xref c c-func docutils literal notranslate"><span class="pre">os_callout_stop()</span></code></a>.</p> |
| <p>There are 2 different options for data structure to use. First is |
| <code class="xref c c-type docutils literal notranslate"><span class="pre">struct</span> <span class="pre">os_callout</span></code>, which is a bare-bones version. You would |
| initialize this with <a class="reference internal" href="#c.os_callout_init" title="os_callout_init"><code class="xref c c-func docutils literal notranslate"><span class="pre">os_callout_init()</span></code></a>.</p> |
| <p>Second option is <code class="xref c c-type docutils literal notranslate"><span class="pre">struct</span> <span class="pre">os_callout_func</span></code>. This you can use if you |
| expect to have multiple different types of timers in your task, running |
| concurrently. The structure contains a function pointer, and you would |
| call that function from your task’s event processing loop.</p> |
| <p>Time unit when arming the timer is OS ticks. This rate of this ticker |
| depends on the platform this is running on. You should use OS define |
| <code class="docutils literal notranslate"><span class="pre">OS_TICKS_PER_SEC</span></code> to convert wallclock time to OS ticks.</p> |
| <p>Callout timer fires out just once. For periodic timer type of operation |
| you need to rearm it once it fires.</p> |
