This temporary space is automatically freed on return.<br><br>I am planning on using it for some dimension sized array in compiled templateless code, in lieu of C99 dynamic stack based arrays.<br><br>Best as I can tell Windows defines it as _alloca, so a little CMake try compile is going to be needed, not a big deal.<br><br>Thanks,<br>Brad <br>_______________________________________________<br>Powered by www.kitware.com<br><br>Visit other Kitware open-source projects at<br>http://www.kitware.com/opensource/opensource.html<br><br>Kitware offers ITK Training Courses, for more information visit:<br>http://kitware.com/products/protraining.php<br><br>Please keep messages on-topic and check the ITK FAQ at:<br>http://www.itk.org/Wiki/ITK_FAQ<br><br>Follow this link to subscribe/unsubscribe:<br>http://www.itk.org/mailman/listinfo/insight-developers<br></div></body></html>
