I hope to design an interface of a function like this (not in OO way) :
sub tell_error
{ print "Error for @_" }
sub Check_err
{ my %argv = @_;
....
....
}
Check_err ( TYPE => [1, 1, \&tell_error('Type')], DATA => [ 1, 2, \&tell_error
('Data')] );
In Check_err, I want &tell_error ('Type') runs when ${argv{TYPE}}[0] &
${argv{TYPE}}[1] both == 1
but do nothing if that's not the case... $argv{DATA} also doing the same thing...
What I've wrote make tell_error directly run before I go inside Check_err... Any
pointers ?
Must I pass in a $scalar code and eval it ?
Thanks in advise.
