19*c54f35caSApple OSS Distributions<dt><var>host_security</var>
20*c54f35caSApple OSS Distributions<dd>
21*c54f35caSApple OSS Distributions[in security send right] The host's security port.

24*c54f35caSApple OSS Distributions<dd>
25*c54f35caSApple OSS Distributions[in task send right] The port for the task from which to draw the child
26*c54f35caSApple OSS Distributionstask's port rights and address space.

32*c54f35caSApple OSS Distributions<dt><var>audit_token</var>
33*c54f35caSApple OSS Distributions<dd>
34*c54f35caSApple OSS Distributions[in scalar] The task's audit token.
35*c54f35caSApple OSS Distributions<p>
36*c54f35caSApple OSS Distributions<dt><var>ledgers</var>
37*c54f35caSApple OSS Distributions<dd>
38*c54f35caSApple OSS Distributions[pointer to in array of ledger send rights] The set of ledgers from which the
39*c54f35caSApple OSS Distributionstask will draw its resources.
40*c54f35caSApple OSS Distributions<p>

42*c54f35caSApple OSS Distributions<dd>
43*c54f35caSApple OSS Distributions[in scalar] Address space inheritance indicator. If true, the child task in-
44*c54f35caSApple OSS Distributionsherits the address space of the parent task. If false, the kernel assigns

51*c54f35caSApple OSS Distributions<h3>DESCRIPTION</h3>
52*c54f35caSApple OSS Distributions<p>
53*c54f35caSApple OSS DistributionsThe <strong><strong>host_security_create_task_token</strong> function creates a new task from
54*c54f35caSApple OSS Distributions<var>parent_task</var> with explicit security and audit token values, returning the name of the
55*c54f35caSApple OSS Distributionsnew task in the parameter specified by <var>child_task</var>. Other than the security and audit token values, the child task
56*c54f35caSApple OSS Distributionsis as if created by <strong>task_create</strong>.
57*c54f35caSApple OSS Distributions<h3>NOTES</h3>
58*c54f35caSApple OSS Distributions<p>
59*c54f35caSApple OSS DistributionsThe host security port is a privileged port given to the system
60*c54f35caSApple OSS Distributionsbootstrap task for the use of this call.
61*c54f35caSApple OSS Distributions<h3>RETURN VALUES</h3>
62*c54f35caSApple OSS Distributions<dl>
63*c54f35caSApple OSS Distributions<p>
64*c54f35caSApple OSS Distributions<dt> <strong>KERN_INVALID_SECURITY</strong>
65*c54f35caSApple OSS Distributions<dd>
66*c54f35caSApple OSS DistributionsThe value of <var>host_security</var> does not specify the security port for the host on which task lies.
