Re: Trouble getting size of list returned from sub

in reply to Trouble getting size of list returned from sub

Could adding an evaluation to the end of the sub something like;

sub gettinglist{ $ListItemReturnedCount++ if { Item retrieved }; return $ListItemReturnedCount; }

be a possible alternative? Ok, perhaps if you are debugging but not for production as a very unexpectedly short list would be returned to a calling routine somewhere. So, seeing as the sub is returning a list anyway. Could you not retrieve the number from some other place, for example from the sub/routine to where the list is called from?

    Of course this could be easily solved if one can edit the subroutine. However, as the poster noted, it's someone else's code and an XS sub, not a Perl sub.

    Should cpanminus be part of the standard Perl release?
