If you've made other modifications 'fp' might have been the hapless victim of corruption; however. Note that some C libraries will check for and throw away NULL fcloses silently, others will not check and memory corruption results; fclose as found in MSVC++ does a direct assert() on the condition. -Mysid -- +---------------------------------------------------------------+ | FAQ: http://qsilver.queensu.ca/~fletchra/Circle/list-faq.html | | Archives: http://post.queensu.ca/listserv/wwwarch/circle.html | +---------------------------------------------------------------+
