NAME
       PAPI_start_counters -

       Start counting hardware events.

SYNOPSIS
Detailed Description
       @par C Interface:
       int PAPI_start_counters( int *events, int array_len );

       Parameters:
	   *events an array of codes for events such as PAPI_INT_INS or a native event code
	   array_len the number of items in the *events array

       Return values:
	   PAPI_EINVAL One or more of the arguments is invalid.
	   PAPI_EISRUN Counters have already been started, you must call PAPI_stop_counters()
	   before you call this function again.
	   PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable.
	   PAPI_ENOMEM Insufficient memory to complete the operation.
	   PAPI_ECNFLCT The underlying counter hardware cannot count this event and other events
	   in the EventSet simultaneously.
	   PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware.

       PAPI_start_counters() starts counting the events named in the *events array. This function
       cannot be called if the counters have already been started. The user must call
       PAPI_stop_counters() to stop the events explicitly if he/she wants to call this function
       again. It is the user's responsibility to choose events that can be counted simultaneously
       by reading the vendor's documentation. The length of the *events array should be no longer
       than the value returned by PAPI_num_counters().

       if( PAPI_start_counters( Events, num_hwcntrs ) != PAPI_OK )
	   handle_error(1);
