<br>
The goal is to add whatever can be added to the Newlib C, it will<br>
eventually make its way into RTEMS (when we bump to a snapshot/release<br>
of newlib that includes the addition). We prefer to try to get this<br>
POSIX stuff implemented in Newlib. For this, you might want to see if<br>
you can get some advice from Aditya who went through this process 2<br>
years ago or so.<br></blockquote><div>Thanks Gedare, I will try to connect with him. <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
