Nice catch; I was trying to spot it myself, and it is crystal clear now that I go reread the msdn page on SetFilePointer, but I wasn't seeing it on my own. At least it was twice as generous as ftell/fseek failing on files > 2GB - 1 byte. Shoot - now that means I have to fix coreutils ASAP so that the trivial 'cat smallfile >> smallfile' will once again work for snapshot users, now that you correctly took away the non-POSIX seek in exec()! Thanks for the quick turnaround on fixing the cygwin side of this, and for the OP's persistence. And thank goodness for sparse files in NTFS (as I don't really have 4 gig of disk space available in my /tmp). -- Eric Blake -- 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/
