<p>The memfile interface allows you to treat a fixed block of contiguous memory as a file that can be used with Allegro's I/O functions.</p>
<p>These functions are declared in the following header file. Link with allegro_memfile.</p>
<div class="sourceCode"><pre class="sourceCode c"><code class="sourceCode c"> <span class="ot">#include &lt;allegro5/allegro_memfile.h&gt;</span></code></pre></div>
<h1 id="al_open_memfile">al_open_memfile</h1>
<div class="sourceCode"><pre class="sourceCode c"><code class="sourceCode c">ALLEGRO_FILE *al_open_memfile(<span class="dt">void</span> *mem, <span class="dt">int64_t</span> size, <span class="dt">const</span> <span class="dt">char</span> *mode)</code></pre></div>
<p>Returns a file handle to the block of memory. All read and write operations act upon the memory directly, so it must not be freed while the file remains open.</p>
<p>The mode can be any combination of &quot;r&quot; (readable) and &quot;w&quot; (writable). Regardless of the mode, the file always opens at position 0. The file size is fixed and cannot be expanded. The file is always read from/written to in binary mode, which means that no newline translation is performed.</p>
<p>It should be closed with <a href="file.html#al_fclose">al_fclose</a>. After the file is closed, you are responsible for freeing the memory (if needed).</p>
<h1 id="al_get_allegro_memfile_version">al_get_allegro_memfile_version</h1>
<div class="sourceCode"><pre class="sourceCode c"><code class="sourceCode c"><span class="dt">uint32_t</span> al_get_allegro_memfile_version(<span class="dt">void</span>)</code></pre></div>
<p>Returns the (compiled) version of the addon, in the same format as <a href="system.html#al_get_allegro_version">al_get_allegro_version</a>.</p>
