<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>
<span id="XREFfputs"></span><dl>
<dt id="index-fputs">: <em></em> <strong>fputs</strong> <em>(<var>fid</var>, <var>string</var>)</em></dt>
<dt id="index-fputs-1">: <em><var>status</var> =</em> <strong>fputs</strong> <em>(<var>fid</var>, <var>string</var>)</em></dt>
<dd><p>Write the string <var>string</var> to the file with file descriptor <var>fid</var>.
</p>
<p>The string is written to the file with no additional formatting. Use
<code>fdisp</code> instead to automatically append a newline character appropriate
for the local machine.
</p>
<p>Return a non-negative number on success or EOF on error.
</p>
<p><strong>See also:</strong> <a href="Simple-File-I_002fO.html#XREFfdisp">fdisp</a>, <a href="Formatted-Output.html#XREFfprintf">fprintf</a>, <a href="Binary-I_002fO.html#XREFfwrite">fwrite</a>, <a href="Opening-and-Closing-Files.html#XREFfopen">fopen</a>.
</p></dd></dl>
<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.
</p>
<span id="XREFputs"></span><dl>
<dt id="index-puts">: <em></em> <strong>puts</strong> <em>(<var>string</var>)</em></dt>
<dt id="index-puts-1">: <em><var>status</var> =</em> <strong>puts</strong> <em>(<var>string</var>)</em></dt>
<dd><p>Write a string to the standard output with no formatting.
</p>
<p>The string is written verbatim to the standard output. Use <code>disp</code> to
automatically append a newline character appropriate for the local machine.
</p>
<p>Return a non-negative number on success and EOF on error.
