Taking individual values from return of a function

gayu_justin has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

I have function with return value like below :


return { red    => { sla => $sla_red, eta => $eta_red, pending => $red
+_pending},
                         green  => { sla => $sla_green, eta => $eta_gr
+een, pending => $green_pending},
                        };
[download]

I want to take only $sla_red and $sla_green each time the function calls in another cgi file. Please help me doing this.

Hi, what keeps you away from just taking these two values? You could use a wrapper if you need: `sub your_wrapper { my $ret = your_function(@_); return ($ret->{red}->{sla}, $ret->{green}->{sla}); } my ($val1, $val2) = your_wrapper('bla', 'blub');` [download] Regards McA	[reply] [d/l]

Possibly lack of knowledge about reference usage.	[reply]

I want to take only `$sla_red` and `$sla_green` each time the function calls... `my $href = function_call(); my( $red, $green ) = map { $href->{$_}{sla} } qw( red green );` [download] ...in another cgi file. That last part is too vague. Please clarify. Dave	[reply] [d/l] [select]

The function is written in one file and i want the variables in another file.	[reply]

... i want the variables in another file. That's still too vague for me to understand. Do you mean "I want the values of the variables to be written to another file", or "I want to access those variables from a part of my program contained in another file", or ...?	[reply]
