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);

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);
       *
