To be more preciser, the above statements echo the return code on the screen. The way to get the return code with the above statements in your script is:

Code:
retval=`awk -f input_check.awk strings.txt`

To return an exit code you can use the exit statement of awk:

Code:
exit(ReturnCode)

The return code can then be retrieved with:

Code:
retval=`echo $?`

PAPI_detach(3)							       PAPI							    PAPI_detach(3)

NAME

       PAPI_detach -

       Detach PAPI event set from previously specified thread id and restore to executing thread.

SYNOPSIS

Detailed Description
       @par C Interface:
       int PAPI_detach( int  EventSet, unsigned long  tid );

       PAPI_detach is a wrapper function that calls PAPI_set_opt to allow PAPI to
       monitor performance counts on a thread other than the one currently executing.
       This is sometimes referred to as third party monitoring.
       PAPI_attach connects the specified EventSet to the specifed thread;
       PAPI_detach breaks that connection and restores the EventSet to the
       original executing thread.

       @param EventSet
	   An integer handle for a PAPI EventSet as created by PAPI_create_eventset.
       @param tid
	   A thread id as obtained from, for example, PAPI_list_threads or PAPI_thread_id.

       @retval PAPI_ECMP
	   This feature is unsupported on this component.
       @retval PAPI_EINVAL
	   One or more of the arguments is invalid.
       @retval PAPI_ENOEVST
	   The event set specified does not exist.
       @retval PAPI_EISRUN
	   The event set is currently counting events.

       @par Examples:

       *   int EventSet = PAPI_NULL;
       *   unsigned long pid;
       *   pid = fork( );
       *   if ( pid <= 0 )
       *   exit( 1 );
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   exit( 1 );
       *   // Add Total Instructions Executed to our EventSet
       *   if ( PAPI_add_event( EventSet, PAPI_TOT_INS ) != PAPI_OK )
       *   exit( 1 );
       *   // Attach this EventSet to the forked process
       *   if ( PAPI_attach( EventSet, pid ) != PAPI_OK )
       *   exit( 1 );
       *
