NAME
PAPI_list_events - list the events in an event set SYNOPSIS
Detailed Description List the events in an event set. PAPI_list_events() returns an array of events and a count of the total number of events in an event set. This call assumes an initialized PAPI library and a successfully created event set. C Interface #include <papi.h> int PAPI_list_events(int *EventSet, int *Events, int *number ); Parameters: EventSet An integer handle for a PAPI event set as created by PAPI_create_eventset *Events A pointer to a preallocated array of codes for events, such as PAPI_INT_INS. No more than *number codes will be stored into the array. *number On input, the size of the Events array, or maximum number of event codes to be returned. A value of 0 can be used to probe an event set. On output, the number of events actually in the event set. This value may be greater than the actually stored number of event codes. Return values: PAPI_EINVAL PAPI_ENOEVST Examples: if (PAPI_event_name_to_code("PAPI_TOT_INS",&EventCode) != PAPI_OK) exit(1); if (PAPI_add_event(EventSet, EventCode) != PAPI_OK) exit(1); Convert a second event name to an event code if (PAPI_event_name_to_code("PAPI_L1_LDM",&EventCode) != PAPI_OK) exit(1); if (PAPI_add_event(EventSet, EventCode) != PAPI_OK) exit(1); number = 0; if(PAPI_list_events(EventSet, NULL, &number)) exit(1); if(number != 2) exit(1); if(PAPI_list_events(EventSet, Events, &number)) exit(1); * See Also: PAPI_event_code_to_name PAPI_event_name_to_code PAPI_add_event PAPI_create_eventset Fortran Interface: #include 'fpapi.h' PAPI_list_events( C_INT EventSet, C_INT(*) Events, C_INT number, C_INT check ) See Also: PAPI_list_events Author Generated automatically by Doxygen for PAPI from the source code.

NAME
PAPI_remove_events - Remove an array of hardware event codes 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 current platform, run papi_native_avail in the PAPI distribution. It should be noted that PAPI_remove_events can partially succeed, exactly like PAPI_add_events. C Prototype: #include <papi.h> int PAPI_remove_events( int EventSet, int * EventCode, int number ); Parameters: EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset *Events an array of defined events number an integer indicating the number of events in the array *EventCode Return values: Positive integer The number of consecutive elements that succeeded before the error. PAPI_EINVAL One or more of the arguments is invalid. PAPI_ENOEVST The EventSet specified does not exist. PAPI_EISRUN The EventSet is currently counting events. PAPI_ECNFLCT The underlying counter hardware can not count this event and other events in the EventSet simultaneously. PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware. 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); // Remove event ret = PAPI_remove_events(EventSet, Events, 2); if (ret != PAPI_OK) handle_error(ret); * @see PAPI_cleanup_eventset PAPI_destroy_eventset PAPI_event_name_to_code PAPI_presets PAPI_add_event PAPI_add_events.fi Author Generated automatically by Doxygen for PAPI from the source code.
