NAME

       PAPI_get_overflow_event_index -

       converts an overflow vector into an array of indexes to overflowing events

SYNOPSIS

Detailed Description
       @param EventSet
	   an integer handle to a PAPI event set as created by PAPI_create_eventset
       @param overflow_vector
	   a vector with bits set for each counter that overflowed.
	   This vector is passed by the system to the overflow handler routine.
       @param *array
	   an array of indexes for events in EventSet.
	   No more than *number indexes will be stored into the array.
       @param *number
	   On input the variable determines the size of the array.
	   On output the variable contains the number of indexes in the array.

       @retval PAPI_EINVAL
	   One or more of the arguments is invalid. This could occur if the overflow_vector is empty (zero), if the array or number pointers are NULL, if the value of number is less than one, or if the EventSet is empty.
       @retval PAPI_ENOEVST
       The EventSet specified does not exist.
       @par Examples

	       void handler(int EventSet, void *address, long_long overflow_vector, void *context){
	       int Events[4], number, i;
	       int total = 0, retval;
	       printf("Overflow #%d Handler(%d) Overflow at %p! vector=0x%llx0,
	       total, EventSet, address, overflow_vector);
	       total++;
	       number = 4;
	       retval = PAPI_get_overflow_event_index(EventSet,
	       overflow_vector, Events, &number);
	       if(retval == PAPI_OK)
	       for(i=0; i<number; i++) printf("Event index[%d] = %d", i, Events[i]);}

NAME

       PAPI_remove_named_event -

       removes a named hardware event from a PAPI event set.

SYNOPSIS

Detailed Description
       A hardware event can be either a PAPI Preset or a native hardware
       event code.  For a list of PAPI preset events, see PAPI_presets or
       run the papi_avail utility in the PAPI distribution.  PAPI Presets
       can be passed to PAPI_query_event to see if they exist on the
       underlying architecture.  For a list of native events available on
       the current platform, run papi_native_avail in the PAPI distribution.

       @par C Interface:
       int PAPI_remove_event( int  EventSet, int  EventCode );

       @param[in] EventSet
	  -- an integer handle for a PAPI event set as created
		by PAPI_create_eventset
       @param[in] EventName
	  -- a defined event such as PAPI_TOT_INS or a native event.

       @retval PAPI_OK
	   Everything worked.
       @retval PAPI_EINVAL
	   One or more of the arguments is invalid.
       @retval PAPI_ENOINIT
	   The PAPI library has not been initialized.
       @retval PAPI_ENOEVST
	   The EventSet specified does not exist.
       @retval PAPI_EISRUN
	   The EventSet is currently counting events.
       @retval PAPI_ECNFLCT
	   The underlying counter hardware can not count this
		  event and other events in the EventSet simultaneously.
       @retval PAPI_ENOEVNT
	   The PAPI preset is not available on the underlying hardware.

       @par Example:

       *   char EventName = "PAPI_TOT_INS";
       *   int EventSet = PAPI_NULL;
       *   int ret;
       *
       *   // Create an empty EventSet
       *   ret = PAPI_create_eventset(&EventSet);
       *   if (ret != PAPI_OK) handle_error(ret);
       *
       *   // Add Total Instructions Executed to our EventSet
       *   ret = PAPI_add_named_event(EventSet, EventName);
       *   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);
       *
       *   // Remove event
       *   ret = PAPI_remove_named_event(EventSet, EventName);
       *   if (ret != PAPI_OK) handle_error(ret);
       *
