RE: [Arsperl-users] Problem with ars_GetListContainer

[Stapff, T. <thi...@ma...>]

Peter,

the problem here seems to be the "|| die ..." operation. From the
"perlop"-manpage: 

 The "||" and "&&" operators return the last value evaluated


It should work as intended if you try it this way:

  my @what = ars_GetListContainer($ctrl, 0,
		&ARS::AR_HIDDEN_INCREMENT, 
		&ARS::ARCON_GUIDE,
		&ARS::ARCON_APP, 
  );
  die "ars_GetListContainer error: $ars_errstr\n" if ! @what;
  print join(' | ',@what), "\n";  # _DEBUG_



Regards,
Thilo Stapff

Thanks Richard and Ian for your replies. I should have said in my original
email that my code started with the example that used @l. In this case I
appear to get a single element which is a reference to a hash. However hard
I look at it, my conclusion is always that I just get back a single hash
describing a single container.

Unfortunately I don't have the ability to recompile the module otherwise I
would have put debugging in the code to see what was actually being returned
by the underlying C call.


Regards, 

Petet
