Eric Blake <ebb9 <at> byu.net> writes: > Somehow, when the file size is huge, cygwin is not properly propogating that an > O_APPEND bit (0x9 in the flags printed from F_GETFL) means that the initial > offset of fd 1 is the end of the file. (And it would be nice if strace would > show the initial lseek offset of all inherited fd's when spawning a process). Actually, there is another cygwin bug. POSIX requires that this assertion succeed: assert (0 == lseek (open("existing", O_WRONLY | O_APPEND), 0, SEEK_CUR)); which is currently not the case on small files. The file position is only moved as part of the subsequent write()s. -- 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/
