<p>The Change Thread Status (QteChangeThreadStatus) API changes the debug status for threads being debugged.</p>
|
||
|
|
|
||
|
|
<blockquote>
|
||
|
|
<p><strong>Note:</strong> A job may have several threads, each of which are debugged if the job is debugged. By default, the current thread is the initial thread of the debugged job, or the thread at a debug stop.</p>
|
||
|
|
</blockquote>
|
||
|
|
|
||
|
|
<p>Before the debug status of a thread can be changed, the thread must be stopped or halted by debug support. If any thread specified in the thread array has not been stopped or halted by debug support, an error is returned to the API caller and the debug status of all threads is unchanged.</p>
|
||
|
|
|
||
|
|
<p>Threads debugging is supported if a service job is used to debug a job that was spawned by native threads support. If this is not the debug environment present when this API is called, a CPF958B error is returned.</p>
