perl hash
Hi i am reading one file and creating Hash from the contents of it my issue is there are 3 different files in 3 different locations having same structure so for parsing these files i have one subroutine which returns hash after reading all the 3 files i need to create consolidated hash from three how to do it ?

i managed to do it just wondering are there any better ways to do the same ?

Code:
output of data::dumper 

   direct =>{ 
                 1 => {
                           'one' => '1',
                           'two' => '2',
                           'thr'  => '3',
                         }
                } ;
  indirect =>{ 
                 1 => {
                           'one' => '1',
                           'two' => '2',
                           'thr'  => '3',
                         }
                } ;

i want to copy this in new hash at the end 

# $ret is original hash 
# $n is new hash 
foreach my $k ( keys %$ret )
{
    foreach my $m ( keys %{$ret->{$k}} )
    {
        foreach my $n ( keys %{$ret->{$k}->{$m}} )
        {
            $n->{$k}->{$m}->{$n} = $ret->{$k}->{$m}{$n}
        }
    }
}

above code is working just wondering is this the right way ?? or there are any better ways to do this . i dont want to use module for this

PAPI_reset(3)							       PAPI							     PAPI_reset(3)

NAME

       PAPI_reset -

       Reset the hardware event counts in an event set.

SYNOPSIS

Detailed Description
       @par C Prototype:
	       int PAPI_reset( int EventSet );

       @param EventSet
	   an integer handle for a PAPI event set as created by PAPI_create_eventset

       @retval PAPI_OK
       @retval PAPI_ESYS
	   A system or C library call failed inside PAPI, see the errno variable.
       @retval PAPI_ENOEVST
	   The EventSet specified does not exist.

       PAPI_reset() zeroes the values of the counters contained in EventSet.
       This call assumes an initialized PAPI library and a properly added event set

       @par Example:

       int EventSet = PAPI_NULL;
       int Events[] = {PAPI_TOT_INS, PAPI_FP_OPS};
       int ret;

       // Create an empty EventSet
       ret = PAPI_create_eventset(&EventSet);
       if (ret != PAPI_OK) handle_error(ret);

       // Add two events to our EventSet
       ret = PAPI_add_events(EventSet, Events, 2);
       if (ret != PAPI_OK) handle_error(ret);

       // Start counting
       ret = PAPI_start(EventSet);
       if (ret != PAPI_OK) handle_error(ret);

       // Stop counting, ignore values
       ret = PAPI_stop(EventSet, NULL);
       if (ret != PAPI_OK) handle_error(ret);

       // reset the counters in this EventSet
       ret = PAPI_reset(EventSet);
       if (ret != PAPI_OK) handle_error(ret);
