Hi,

In my system popen2 is broken. Bellow is a run of the suggested 
help example. As soon as the write pipe to the process is closed, 
it starts writing to octave, but not to the read pipe: 

octave:380>   [in, out, pid] = popen2 ("sort", "-nr");
  fputs (in, "these\n");
  fputs (in, "are\n");
  fputs (in, "some\n");
  fputs (in, "strings\n");
  fclose (in);
octave:381>   fputs (in, "these\n");
octave:382>   fputs (in, "are\n");
octave:383>   fputs (in, "some\n");
octave:384>   fputs (in, "strings\n");
octave:385>   fclose (in);
these
strings
some
are

Thanks,
Joao
