NAME

Devel::Caller::Perl - Perl only implementation.

SYNOPSIS

            

              
              
use Devel::Caller::Perl qw[called_args];
sub permute_args {
  my @args = @_;
  my @caller_args = called_args( 0 );
   
  my %caller_args =
    map { $_ => $caller_args[$_] } 0 .. $#caller_args;
   
  return \%caller_args;
}
sub dodad {
  my $args = permute_args;
  print $args->{0};
  # ...
}
            
          

ABSTRACT

This module allows a method to get at arguments passed to subroutines higher up in the call stack.

DESCRIPTION

FUNCTIONS

called_args [LEVEL]

called_args returns the arguments to the subroutine at LEVEL in the call stack. If no level is specified, 0 (zero) is assumed, that being our caller. If a list is expected, it will be returned. When a scalar is expected, a list reference will be returned.

If you want the number of arguments passed to the subroutine at LEVEL, there's nothing stopping you from getting it from caller.

            

              
              
my $number = (caller $level)[4];
