4<strong>Function</strong> - Optimized creation of a running thread.
5<h3>SYNOPSIS</h3>
6<pre>
7<strong>kern_return_t thread_create_running</strong>
8 <strong>(task_t</strong> <var>parent_task</var>,
9 <strong>thread_state_flavor_t</strong> <var>flavor</var>,
10 <strong>thread_state_t</strong> <var>state</var>,
11 <strong>thread_act_t</strong> <var>child_thread</var><strong>);</strong>

13<h3>PARAMETERS</h3>
14<dl>
15<p>
16<dt> <var>parent_task</var>
17<dd>
18[in task send right]
19The port for the task that is to contain the new
20thread.
21<p>
22<dt> <var>flavor</var>
23<dd>
24[in scalar]
25The type of state to establish. Valid values correspond to
26supported machine architecture features.
27<p>
28<dt> <var>state</var>
29<dd>
30[pointer to in structure]
31State information for the specified thread.
32<p>
33<dt> <var>child_thread</var>
34<dd>
35[out thread send right]
36The kernel-assigned name for the new thread.
37</dl>
38<h3>DESCRIPTION</h3>
39<p>
40The <strong>thread_create_running</strong> function creates a new thread
41within <var>parent_task</var>.
42The new thread has is not suspended. Its initial state is given
43by <var>state</var>. <var>flavor</var> specifies the type of state to set.
44<p>
45The format of the state to set is machine specific; it is defined in
46\*L<mach/thread_status.h>\*O.
47<p>
48The new thread holds a send right for its thread kernel port.
49A send right for the
50thread's kernel port is also returned to the calling task or
51thread in <var>child_thread</var>.
52The new thread's exception ports are set to <strong>MACH_PORT_NULL</strong>.
53<h3>NOTES</h3>
54<p>
55This is an optimized form of the sequence: <strong>thread_create</strong>,
56<strong>thread_set_state</strong>
57and <strong>thread_resume</strong>.
58<h3>RETURN VALUES</h3>
59<p>
60Only generic errors apply.
