Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;"> pos_type ofstream<span class="sy0">::</span><span class="me2">tellp</span><span class="br0">(</span><span class="br0">)</span><span class="sy0">;</span></pre>
<p>
The tellp() function is used with output streams, and returns the current “put”
position of the pointer in the stream.
For example, the following code displays the file pointer as it writes to a
stream:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="kw4">string</span> s<span class="br0">(</span><span class="st0">"In Xanadu did Kubla Khan..."</span><span class="br0">)</span><span class="sy0">;</span>
