PAPI_remove_event(3) PAPI PAPI_remove_event(3) NAME
PAPI_remove_event - removes a hardware event 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 the current platform, run papi_native_avail in the PAPI distribution. @par C Interface: int PAPI_remove_event( int EventSet, int EventCode ); @param[in] EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset @param[in] EventCode -- a defined event such as PAPI_TOT_INS or a native event. @retval PAPI_OK Everything worked. @retval PAPI_EINVAL One or more of the arguments is invalid. @retval PAPI_ENOEVST The EventSet specified does not exist. @retval PAPI_EISRUN The EventSet is currently counting events. @retval PAPI_ECNFLCT The underlying counter hardware can not count this event and other events in the EventSet simultaneously. @retval PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware. @par Example: * int EventSet = PAPI_NULL; * int ret; * * // Create an empty EventSet * ret = PAPI_create_eventset(&EventSet); * if (ret != PAPI_OK) handle_error(ret); * * // Add Total Instructions Executed to our EventSet * ret = PAPI_add_event(EventSet, PAPI_TOT_INS); * 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_event(EventSet, PAPI_TOT_INS); * if (ret != PAPI_OK) handle_error(ret); * See Also: PAPI_cleanup_eventset PAPI_destroy_eventset PAPI_event_name_to_code PAPI_presets PAPI_add_event PAPI_add_events Author Generated automatically by Doxygen for PAPI from the source code.
