PAPI_add_events -
add multiple PAPI presets or native hardware events to an event set
@par C Interface: int PAPI_add_events( int EventSet, int * EventCodes, int number ); PAPI_add_event adds one event to a PAPI Event Set. PAPI_add_events does the same, but for an array of events. @n 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 avail test case 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 current platform, run native_avail test case in the PAPI distribution. For the encoding of native events, see PAPI_event_name_to_code to learn how to generate native code for the supported native event on the underlying architecture. @param EventSet
An integer handle for a PAPI Event Set as created by PAPI_create_eventset. @param *EventCode
An array of defined events. @param number
An integer indicating the number of events in the array *EventCode.
It should be noted that PAPI_add_events can partially succeed,
exactly like PAPI_remove_events. @retval Positive-Integer
The number of consecutive elements that succeeded before the error. @retval PAPI_EINVAL
One or more of the arguments is invalid. @retval PAPI_ENOMEM
Insufficient memory to complete the operation. @retval PAPI_ENOEVST
The event set specified does not exist. @retval PAPI_EISRUN
The event set is currently counting events. @retval PAPI_ECNFLCT
The underlying counter hardware can not count this event and other events
in the event set simultaneously. @retval PAPI_ENOEVNT
The PAPI preset is not available on the underlying hardware. @retval PAPI_EBUG
Internal error, please send mail to the developers. @par Examples:
* int EventSet = PAPI_NULL; * unsigned int native = 0x0; * if ( PAPI_create_eventset( &EventSet ) != PAPI_OK ) * handle_error( 1 ); * // Add Total Instructions Executed to our EventSet * if ( PAPI_add_event( EventSet, PAPI_TOT_INS ) != PAPI_OK ) * handle_error( 1 ); * // Add native event PM_CYC to EventSet * if ( PAPI_event_name_to_code( "PM_CYC", &native ) != PAPI_OK ) * handle_error( 1 ); * if ( PAPI_add_event( EventSet, native ) != PAPI_OK ) * handle_error( 1 ); *
