NAME
PAPI_add_event - add PAPI preset or native hardware event to an event set SYNOPSIS
Detailed Description @par C Interface: int PAPI_add_event( int EventSet, int EventCode ); PAPI_add_event adds one event to a PAPI Event Set. @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 the papi_native_avail utility 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 A defined event such as PAPI_TOT_INS. @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 ); * @see PAPI_cleanup_eventset @n PAPI_destroy_eventset @n PAPI_event_code_to_name @n PAPI_remove_events @n PAPI_query_event @n PAPI_presets @n PAPI_native @n PAPI_remove_event.fi 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.
