[Octave-bug-tracker] [bug #58055] ftell() incorrect on MS Windows platforms if file is not encoded with CRLF line endings

[John W. Eaton]

Follow-up Comment #13, bug #58055 (project octave):

OK, looking again, I see that if you are just using fseek with SEEK_SET to
return to a position returned by ftell, it should work, even in text mode.

If you do something like


fid = fopen ("some_file", "rt");
k = 0;
while (k++ < 100)
  c = fread (fid, 1);
  if (c < 0) break; endif
  printf ("%d: %d\n", ftell (fid), c);
endwhile


on a Windows system when "some_file" uses LF line-endings, does the file
position returned by ftell jump by 2 when the LF character (ASCII 10) is
read?

Or is the incorrect count just a problem when using fgetl/fgets to read the
file?
