<h2>Description</h2>
<p>
<span class="emphasis"><em>ficlose</em></span> can be used to close a file which was opened with <a class="link" href="fiopen.html" title="fiopen"><em class="citetitle">fiopen</em></a>.

</div>
<div class="refsect1" title="Initialization">
<a id="idp19964056"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ihandle</em></span> -- a number which identifies this file (generated by a previous <a class="link" href="fiopen.html" title="fiopen"><em class="citetitle">fiopen</em></a>).
</p>
<p>
<span class="emphasis"><em>Sfilename</em></span> -- A string in double quotes or string variable with the filename. The full path must be given if the file directory is not in the system PATH and is not present in the current directory.

</div>
<div class="refsect1" title="Performance">
<a id="idp19966016"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>ficlose</em></span> closes a file which was previously opened with <a class="link" href="fiopen.html" title="fiopen"><em class="citetitle">fiopen</em></a>. <span class="emphasis"><em>ficlose</em></span> is only needed if you need to read a file written to during the same csound performance, since only when csound ends a performance does it close and save data in all open files. The opcode <span class="emphasis"><em>ficlose</em></span> is useful for instance if you want to save presets within files which you want to be accesible without having to terminate csound.

<p>If you don't need this functionality it is safer not to call <span class="emphasis"><em>ficlose</em></span>, and just let csound close the files when it exits.</p>

<p>
If a files closed with <span class="emphasis"><em>ficlose</em></span> is being accessed by another opcode (like <a class="link" href="fout.html" title="fout"><em class="citetitle">fout</em></a> or <a class="link" href="foutk.html" title="foutk"><em class="citetitle">foutk</em></a>), it will be closed later when it is no longer being used.

<p>This opcode should be used with care, as the file handle will become invalid, and will cause an init error when an opcode tries to access the closed file.</p>
