Hi all,<div><br></div><div>I just found out that you can avoid this automatic interpretation as C string if you use a type alias to char*. This could at least help if an external library forgets the NULL character for that returned char* and makes your VM crash. :-)</div><div><br></div><div>Best,</div><div>Marcel</div><div class="mb_sig"></div><blockquote class="history_container" type="cite" style="border-left-style:solid;border-width:1px; margin-top:20px; margin-left:0px;padding-left:10px;">
