<div id="style_14243507290000000631_BODY">There is a sscanf() implementation in <br>
backends/platform/tizen/sscanf.cpp. I don't know the story behind it, <br>
but it might be a good starting point.<br>
<br>
However, it seems to be missing at the very least floating-point support <br>
and assignment-suppression (e.g. "%*u"), both of which are currently <br>
used by ZVision.<br>
