add multiple PAPI presets or native hardware events to an event set More...
PAPI_add_event adds one event to a PAPI Event Set. PAPI_add_events does the same, but for an array of events.
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.
|EventSet||An integer handle for a PAPI Event Set as created by PAPI_create_eventset.|
|*EventCode||An array of defined events.|
|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.|
|Positive-Integer||The number of consecutive elements that succeeded before the error.|
|PAPI_EINVAL||One or more of the arguments is invalid.|
|PAPI_ENOMEM||Insufficient memory to complete the operation.|
|PAPI_ENOEVST||The event set specified does not exist.|
|PAPI_EISRUN||The event set is currently counting events.|
|PAPI_ECNFLCT||The underlying counter hardware can not count this event and other events in the event set simultaneously.|
|PAPI_ENOEVNT||The PAPI preset is not available on the underlying hardware.|
|PAPI_EBUG||Internal error, please send mail to the developers.|
