[Octave-bug-tracker] [bug #33876] textscan: resuming reading does not work

[Ben Abbott]

Follow-up Comment #1, bug #33876 (project octave):

Coincidently, I just wrote a script that I'd thought was working correctly.
After see the bug report, I checked and found it was not.

Below is a simple script I used to check (using the developer's sources)


fid = fopen ("coordinates.txt", "w");
for n = 1:2:20
  fprintf (fid, "%d %dn", n + [0 1])
endfor
fclose (fid);
fid = fopen ("coordinates.txt", "r");
c1 = textscan (fid, "%d %d", 1)
c2 = textscan (fid, "%d %d", 2)
c3 = textscan (fid, "%d %d", 3)
fclose (fid);


and the result was ...


c1 = 
{
  [1,1] =  1
  [1,2] =  2
}
c2 = 
{
  [1,1] =

     5
     7

  [1,2] =

     6
     8

}
c3 = 
{
  [1,1] =

     11
     13
     15

  [1,2] =

     12
     14
     16

}


It looks like each time textscan is called, and extra line is read, but not
processed.

Philip, can you confirm this is the same problem you've reported? ... or is
there something more?
