38*27b03b36SApple OSS Distributions<h3>DESCRIPTION</h3>
39*27b03b36SApple OSS Distributions<p>
40*27b03b36SApple OSS DistributionsThe <strong>thread_create_running</strong> function creates a new thread
41*27b03b36SApple OSS Distributionswithin <var>parent_task</var>.
42*27b03b36SApple OSS DistributionsThe new thread has is not suspended.  Its initial state is given
43*27b03b36SApple OSS Distributionsby <var>state</var>.  <var>flavor</var> specifies the type of state to set.
44*27b03b36SApple OSS Distributions<p>
45*27b03b36SApple OSS DistributionsThe format of the state to set is machine specific; it is defined in
46*27b03b36SApple OSS Distributions\*L<mach/thread_status.h>\*O.
47*27b03b36SApple OSS Distributions<p>
48*27b03b36SApple OSS DistributionsThe new thread holds a send right for its thread kernel port.
49*27b03b36SApple OSS DistributionsA send right for the
50*27b03b36SApple OSS Distributionsthread's kernel port is also returned to the calling task or
51*27b03b36SApple OSS Distributionsthread in <var>child_thread</var>.
52*27b03b36SApple OSS DistributionsThe new thread's exception ports are set to <strong>MACH_PORT_NULL</strong>.
53*27b03b36SApple OSS Distributions<h3>NOTES</h3>
54*27b03b36SApple OSS Distributions<p>
55*27b03b36SApple OSS DistributionsThis is an optimized form of the sequence: <strong>thread_create</strong>,
56*27b03b36SApple OSS Distributions<strong>thread_set_state</strong>
57*27b03b36SApple OSS Distributionsand <strong>thread_resume</strong>.
58*27b03b36SApple OSS Distributions<h3>RETURN VALUES</h3>
59*27b03b36SApple OSS Distributions<p>
60*27b03b36SApple OSS DistributionsOnly generic errors apply.
