add multiple PAPI presets or native hardware events to an event set More...
@par C Interface: \#include <papi.h> @n 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:
