14<dl>
15<p>
16<dt> <var>target_thread</var> 
17<dd>
18[in thread send right]
19The thread for which to set the execution state. 
20The calling thread cannot specify itself.
21<p>
22<dt> <var>flavor</var> 
23<dd>
24[in scalar]
25The type of state to set.  Valid values correspond to
26supported machine architecture features.

28<dt> <var>new_state</var> 
29<dd>
30[pointer to in structure]
31State information for the specified thread.
32<p>
33<dt> <var>new_state_count</var> 
34<dd>
35[in scalar]
36The size of the buffer (in natural-sized units).

41(for example, the
42machine registers) for <var>target_thread</var>.  <var>flavor</var> specifies the type
43of state to set.
44<p>
45The format of the state to set is machine specific; it is defined in
46<strong>mach/thread_status.h</strong>.
