<br>
If you don't understand a request from someone, please ask them for<br>
more details. It is a waste of everyone's time if you go write code<br>
without understanding the requirements.<br>
<br>
I also see that Joel complained that this test won't run. You need to<br>
add such comments in your commit message or email introduction if a<br>
patch is not expected to work yet, or if you haven't tested it<br>
yourself. In general, sending us patches to review that you haven't<br>
tested is also wasting our time. We don't like to waste our time.<br></blockquote><div>I had asked for elaboration but got no reply</div><div><a href="https://lists.rtems.org/pipermail/devel/2020-April/059299.html" target="_blank">https://lists.rtems.org/pipermail/devel/2020-April/059299.html</a> </div><div>Also, I tested the code and it worked fine I had told that<br></div><div>before adding the time part.<br><a href="https://lists.rtems.org/pipermail/devel/2020-April/059294.html" target="_blank">https://lists.rtems.org/pipermail/devel/2020-April/059294.html</a></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

This "return NULL;" will never be executed. pthread_exit() does not return.<br>
<br>
NULL has a type (void *). This function is declared void, it should<br>
return nothing.<br>
<br>
Thus, an explicit return statement should just be:<br>
return;<br>
while the fall-out of the end of the function can be simply the<br>
closing french brace.<br>

I still don't understand why it is necessary to do this test in a<br>
separate pthread.<br>
