Does using last_write_time leave an opportunity for false negative because it has been updated in between obtaining the value for each filename? Would using creation_time ( if available ) be safer ?

As an alternative, I removed the st_dev test and added a last_write_time test. Documentation also updated. See current CVS. To make it easier to experiment, I also added in the test directory a program equivalent.cpp. This seems to solve the problem. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
