varargout form a DLD function

[Shai Ayal]

Hi all,

I am trying to return a variable number of arguments from a DLD function

//-------------------------------------------------
#include "oct.h"
DEFUN_DLD (test_arg, args, nargout,"")
{
  octave_value_list retval;

  for(int i=0;i<5;i++) retval(i)=i;

  nargout = 5;
  return retval;
}
//-------------------------------------------------


however, I cannot recover these arguments at the command line:

GNU Octave, version 2.1.50 (i686-pc-linux-gnu).
octave:1> test_arg()
ans = 0
octave:2> a{:}=test_arg()
a =
{
  [1,1] = 0
}
octave:3> b=test_arg()
b = 0
octave:4> [a,b,c]=test_arg()
a = 0
b = 1
c = 2

Note that if I know the number of arguments I can get them as in line 4. 
but what if I don't know beforehand ? Is there something similar to 
varargin{:} for output arguments ?
