<a name="index-puts"></a>

<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;stdio.h&gt;
int puts(const char *<var>s</var>);

int _puts_r(struct _reent *<var>reent</var>, const char *<var>s</var>);

</pre></div>
<p><strong>Description</strong><br>
<code>puts</code> writes the string at <var>s</var> (followed by a newline, instead of
the trailing null) to the standard output stream.
</p>
<p>The alternate function <code>_puts_r</code> is a reentrant version.  The extra
argument <var>reent</var> is a pointer to a reentrancy structure.
</p>
<br>
<p><strong>Returns</strong><br>
If successful, the result is a nonnegative integer; otherwise, the
result is <code>EOF</code>.
</p>
<br>
<p><strong>Portability</strong><br>
ANSI C requires <code>puts</code>, but does not specify that the result on
success must be <code>0</code>; any non-negative value is permitted.
</p>
<p>Supporting OS subroutines required: <code>close</code>, <code>fstat</code>, <code>isatty</code>,
<code>lseek</code>, <code>read</code>, <code>sbrk</code>, <code>write</code>.
</p>
