1<h2>thread_get_state</h2> 2<hr> 3<p> 4<strong>Function</strong> - Return the execution state for a thread. 5<h3>SYNOPSIS</h3> 6<pre> 7<strong>kern_return_t thread_get_state</strong> 8 <strong>(thread_act_t</strong> <var>target_thread</var>, 9 <strong>thread_state_flavor_t</strong> <var>flavor</var>, 10 <strong>thread_state_t</strong> <var>old_state</var>, 11 <strong>mach_msg_type_number_t</strong> <var>old_state_count</var><strong>);</strong> 12</pre> 13<h3>PARAMETERS</h3> 14<dl> 15<p> 16<dt> <var>target_thread</var> 17<dd> 18[in thread send right] 19The thread for which the execution state is to be 20returned. The calling thread cannot specify itself. 21<p> 22<dt> <var>flavor</var> 23<dd> 24[in scalar] 25The type of execution state to be returned. Valid values 26correspond to supported machined architectures. 27<p> 28<dt> <var>old_state</var> 29<dd> 30[out structure] 31State information for the specified thread. 32<p> 33<dt> <var>old_state_count</var> 34<dd> 35[in/out scalar] 36On input, the maximum size of the buffer; on output, the 37size returned (in natural-sized units). 38</dl> 39<h3>DESCRIPTION</h3> 40<p> 41The <strong>thread_get_state</strong> function returns the execution 42state (for example, the 43machine registers) for <var>target_thread</var>. flavor specifies the type 44of state information 45returned. 46<p> 47The format of the data returned is machine specific; it is defined in 48\*L<mach/thread_status.h>\*O. 49<h3>RETURN VALUES</h3> 50<p> 51Only generic errors apply. 52<h3>RELATED INFORMATION</h3> 53<p> 54Functions: 55<a href="task_info.html"><strong>task_info</strong></a>, 56<a href="thread_info.html"><strong>thread_info</strong></a>, 57<a href="thread_set_state.html"><strong>thread_set_state</strong></a>. 58
