hello helmut, yes, I have just understood this. <br><br>Sorry for the noise. <br><br>Actually I had to valide write to echo chars on the console. <br>It was not working, so I disabled the plugin as I did not understand all details...<br>
<br>For the \n, it is because, the &quot;write no supported&quot; as it was buffered was echoed far away from the original call, and it was rather complex to trace. <br><br>For the moment I have the same kind of problem with the close call...<br>

&gt; Here is a patch that validates the write function.<br>
<br>
</div>Your patch simply deactivates our libc plugin mechanism for write(). I<br>
admit, that we currently do not support writes to stdout and stderr<br>
out of the box _and_ that the current error message is a bit<br>
misleading. We _do_ support write() but not to the given fd. I will<br>
fix this soon.<br>
<br>
Please read more about the plugin concept here<br>

&gt; I also put a &quot;\n&quot; in the DUMMY macro display.<br>
<br>
</div>Why do you need this additional linebreak? PERR() adds it in<br>
base/include/base/printf.h:73 to the output.<br>
