       PAPI_stop -

       Stop counting hardware events in an event set.

Detailed Description
       C Interface:
	   #include <papi.h>
	    int PAPI_stop( int	EventSet, long long * values );

	   EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset
	   values -- an array to hold the counter values of the counting events

       Return values:
	   PAPI_EINVAL One or more of the arguments is invalid.
	   PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable.
	   PAPI_ENOEVST The EventSet specified does not exist.
	   PAPI_ENOTRUN The EventSet is currently not running.

       PAPI_stop halts the counting of a previously defined event set and the counter values
       contained in that EventSet are copied into the values array Assumes an initialized PAPI
       library and a properly added event set.


	   *  int EventSet = PAPI_NULL;
	   *  long long values[2];
	   *  int ret;
	   *  ret = PAPI_create_eventset(&EventSet);
	   *  if (ret != PAPI_OK) handle_error(ret);
	   *  // Add Total Instructions Executed to our EventSet
	   *  ret = PAPI_add_event(EventSet, PAPI_TOT_INS);
	   *  if (ret != PAPI_OK) handle_error(ret);
	   *  // Start counting
	   *  ret = PAPI_start(EventSet);
	   *  if (ret != PAPI_OK) handle_error(ret);
	   *  poorly_tuned_function();
	   *  ret = PAPI_stop(EventSet, values);
	   *  if (ret != PAPI_OK) handle_error(ret);
	   *  printf("%lld\n",values[0]);
