[Octave-bug-tracker] [bug #63462] sscanf reports incorrect number of output values.

[anonymous]

Follow-up Comment #16, bug #63462 (project octave):

I don't know exactly why, but it seems that the following patch fixes the
issue:

diff -r b69d89906ae9 libinterp/corefcn/oct-stream.cc

             double tmp;
 
-            if (octave_scan (is, *elt, &tmp))
+            if (octave_scan (is, *elt, &tmp).good())
               {
                 if (! discard)
                   retval = tmp;


When applying the patch, I get this output:

[a,b,c,d,cnt]=sscanf("1 abcdefg 1.5\n","%d %s %g %g","C")
a = 1
b = abcdefg
c = 1.5000
d = [](0x0)
cnt = 3
