From: steph@candide.cs.uchicago.edu (Stephen Bailey) Subject: ftell & fgetpos bug in b18. 1 Sep 1997 15:59:04 -0700 Sender: mail@cygnus.com Approved: cygnus.gnu-win32@cygnus.com Distribution: cygnus Message-ID: <9709011817.AA01305.cygnus.gnu-win32@candide.cs.uchicago.edu> Original-To: gnu-win32@cygnus.com Original-Sender: owner-gnu-win32@cygnus.com ftell and fgetpos report incorrect positions under some circumstances in B18. I am running on Windows NT 4.0 (SP3). If you run the program included below with the /* comment me out */ line commented out, ftell erroneously reports ``5'' for the position in the (existing, and sufficiently large) file foo.txt. With this line in, ftell correctly reports ``2'' as the position in the input file. Steph ------------------------ftelltst.c------------------------------------ #include main () { FILE *f; long int p; int c; f = fopen("foo.txt", "r"); (void) ftell(f); /* comment me out */ c = getc(f); c = getc(f); p = ftell(f); fprintf(stderr,"Position: %d\n", p); } - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
