From: fseibel AT cfa DOT harvard DOT edu (Fred Seibel) Subject: Problem with fsetpos 20 Nov 1997 23:27:35 -0800 Message-ID: <01bcf5b7$190639f0$162085ce.cygnus.gnu-win32@0HNER.sprintmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit To: I have a UNIX program that makes extensive use of fgetpos and fsetpos to move around a file. I have discovered that fsetpos with values of offset greater than ~ 2000L misses the corrrect value. The error is 16 at 2000 and 179 at 10000. I am running WindowsNT 4.0 Workstation, with Service Patch 3. I am running b18. This error can be detected by inspection using gdb. Open a text file a trivial program. main(){ fp = fopen("foo.txt", "r"); fsetpos(fp, 2000L, SEEK_SET); gdb>print *fp shows the next text that will be read. Open file in emacs and position to char 2000. Observe that the file seems to be positioned at 1984. hmmmm.
