https://devzone.nordicsemi.com/f/nordic-q-a/111678/get-the-number-of-items-in-a-fcbI need to get the number of items stored in a fcb and there doesn&#39;t seem to be an easy way to get the count from the current read position (fcb_entry struct). Can anyone advise on a good approach? Some solutions I&#39;ve considered: * Use fcb_getnexten-USTelligent Community 13Wed, 31 Jul 2024 08:59:26 GMThttps://devzone.nordicsemi.com/thread/496372?ContentTypeID=1Wed, 31 Jul 2024 08:59:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1dee6aa5-8267-4e3f-a117-8fb668e4c1d2Shahin97<p><a href="https://devzone.nordicsemi.com/members/dwalks">dwalks</a>&nbsp;<br /><br />For context, <a class="reference internal" title="fcb_getnext" href="https://docs.zephyrproject.org/latest/services/storage/fcb/fcb.html#c.fcb_getnext"><code class="xref c c-func docutils literal notranslate"><span class="pre">fcb_getnext()</span></code></a>,<span>&nbsp;followed by a&nbsp;&nbsp;<a class="reference internal" title="flash_area_read" href="https://docs.zephyrproject.org/latest/services/storage/flash_map/flash_map.html#c.flash_area_read"><code class="xref c c-func docutils literal notranslate"><span class="pre">flash_area_read()</span></code></a>&nbsp;takes me about 1ms.

I have not worked with FCB myself, so I have not tried to profile it, but it doesn&#39;t seem like it should be that slow. Maybe you can time the execution first to see if it&#39;s worth optimizing.
