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. |
