<h4><a name="tag_03_567_08"></a>RATIONALE</h4>

|
|
|
<blockquote>
|
|
<p>The <i>pthread_self</i>() function provides a capability similar to the <a href="../functions/getpid.html"><i>getpid</i>()</a>
|
|
function for processes and the rationale is the same: the creation call does not provide the thread ID to the created thread.</p>
