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.

NAME
PAPI_get_multiplex - Get the multiplexing status of specified event set. SYNOPSIS
Detailed Description C Interface: #include <papi.h> int PAPI_get_multiplex( int EventSet ); Fortran Interface: #include fpapi.h PAPIF_get_multiplex( C_INT EventSet, C_INT check ) Parameters: EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset Return values: PAPI_OK PAPI_EINVAL One or more of the arguments is invalid, or the EventSet is already multiplexed. PAPI_ENOEVST The EventSet specified does not exist. PAPI_EISRUN The EventSet is currently counting events. PAPI_ENOMEM Insufficient memory to complete the operation. PAPI_get_multiplex tests the state of the PAPI_MULTIPLEXING flag in the specified event set, returning TRUE if a PAPI event set is multiplexed, or FALSE if not. Example: * int EventSet = PAPI_NULL; * int ret; * * // Create an empty EventSet * ret = PAPI_create_eventset(&EventSet); * if (ret != PAPI_OK) handle_error(ret); * * // Bind it to the CPU component * ret = PAPI_assign_eventset_component(EventSet, 0); * if (ret != PAPI_OK) handle_error(ret); * * // Check current multiplex status * ret = PAPI_get_multiplex(EventSet); * if (ret == TRUE) printf("This event set is ready for multiplexing.") * if (ret == FALSE) printf("This event set is not enabled for multiplexing.") * if (ret < 0) handle_error(ret); * * // Turn on multiplexing * ret = PAPI_set_multiplex(EventSet); * if ((ret == PAPI_EINVAL) && (PAPI_get_multiplex(EventSet) == TRUE)) * printf("This event set already has multiplexing enabled0); * else if (ret != PAPI_OK) handle_error(ret); * See Also: PAPI_multiplex_init PAPI_set_opt PAPI_create_eventset Author Generated automatically by Doxygen for PAPI from the source code.
