<p>Once a file has been opened for writing a string can be written to the
file using the <code>fputs</code> function. The following example shows
how to write the string ‘<samp>Free Software is needed for Free Science</samp>’
to the file ‘<samp>free.txt</samp>’.
</p>
<div class="example">
<pre class="example">filename = "free.txt";
fid = fopen (filename, "w");
fputs (fid, "Free Software is needed for Free Science");
fclose (fid);
</pre></div>
<a name="XREFfputs"></a><dl>
<dt><a name="index-fputs"></a>Built-in Function: <em></em> <strong>fputs</strong> <em>(<var>fid</var>, <var>string</var>)</em></dt>
<dd><p>Write a string to a file with no formatting.
</p>
<p>Return a non-negative number on success and EOF on error.
</p>

<p>A function much similar to <code>fputs</code> is available for writing data
to the screen. The <code>puts</code> function works just like <code>fputs</code>
except it doesn’t take a file pointer as its input.
