<p>Once a file has been opened for writing a string can be written to the
file using the <code class="code">fputs</code> function. The following example shows
how to write the string ‘<samp class="samp">Free Software is needed for Free Science</samp>’
to the file ‘<samp class="samp">free.txt</samp>’.
</p>
<div class="example">
<div class="group"><pre class="example-preformatted">filename = "free.txt";
fid = fopen (filename, "w");
fputs (fid, "Free Software is needed for Free Science");
fclose (fid);
</pre></div></div>
<a class="anchor" id="XREFfputs"></a><span style="display:block; margin-top:-4.5ex;"> </span>
<dl class="first-deftypefn">
<dt class="deftypefn" id="index-fputs"><span><code class="def-type"><var class="var">status</var> =</code> <strong class="def-name">fputs</strong> <code class="def-code-arguments">(<var class="var">fid</var>, <var class="var">string</var>)</code><a class="copiable-link" href="#index-fputs"> ¶</a></span></dt>
<dd><p>Write the string <var class="var">string</var> to the file with file descriptor <var class="var">fid</var>.
</p>
<p>The string is written to the file with no additional formatting. Use
<code class="code">fdisp</code> instead to automatically append a newline character appropriate
for the local machine.
</p>
<p>The optional output <var class="var">status</var> is 0 for success, or -1 if an error was
encountered.
</p>
<p><strong class="strong">See also:</strong> <a class="ref" href="Simple-File-I_002fO.html#XREFfdisp">fdisp</a>, <a class="ref" href="Formatted-Output.html#XREFfprintf">fprintf</a>, <a class="ref" href="Binary-I_002fO.html#XREFfwrite">fwrite</a>, <a class="ref" href="Opening-and-Closing-Files.html#XREFfopen">fopen</a>.
</p></dd></dl>
<p>A function much similar to <code class="code">fputs</code> is available for writing data
to the screen. The <code class="code">puts</code> function works just like <code class="code">fputs</code>
except it doesn’t take a file pointer as its input.
</p>
<a class="anchor" id="XREFputs"></a><span style="display:block; margin-top:-4.5ex;"> </span>
<dl class="first-deftypefn">
<dt class="deftypefn" id="index-puts"><span><code class="def-type"><var class="var">status</var> =</code> <strong class="def-name">puts</strong> <code class="def-code-arguments">(<var class="var">string</var>)</code><a class="copiable-link" href="#index-puts"> ¶</a></span></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 class="code">disp</code> to
automatically append a newline character appropriate for the local machine.
</p>
<p>The optional output <var class="var">status</var> is 0 for success, or -1 if an error was
encountered.
