The\rinitial value of a task's security and audit tokens is that of its\rparent.\r<h3>NOTES</h3>\r<p>\rThe host security port is a privileged port given to the system\rbootstrap task for the use of this call.\r<h3>RETURN VALUES</h3>\r<dl>\r<p>\r<dt> <strong>KERN_INVALID_SECURITY</strong>\r<dd>\rThe value of <var>host_security</var> does not specify the security port for the host on which task lies.\r</dl>\r<h3>RELATED INFORMATION</h3>\r<p>\rFunctions:\r<a href="task_create.html"><strong>task_create</strong></a>,\r<a href="task_info.html"><strong>task_info</strong></a>,\r<a href="mach_msg.html"><strong>mach_msg</strong></a>.\r
