Thank you very much for your advice. I will explore malloc_usable_size as you suggested.

It's at least a Microsoft extension, but may be present in other compiler libraries. However, it sounds like it's not available in cygwin's C library (newlib). You may want to see if malloc_usable_size can be substituted (see man malloc for details). stephan(); -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
