<h4><a name="tag_03_659_03"></a>DESCRIPTION</h4>
|
|
|
|
<blockquote>
|
|
<p>If the calling process is not already a session leader, <i>setpgrp</i>() sets the process group ID of the calling process to the
|
|
process ID of the calling process. If <i>setpgrp</i>() creates a new session, then the new session has no controlling terminal.</p>
|
|
|
|
<p>The <i>setpgrp</i>() function has no effect when the calling process is a session leader.</p>
