PAPI_start_counters(3) PAPI PAPI_start_counters(3)NAMEPAPI_start_counters - Start counting hardware events.SYNOPSISDetailed Description @par C Interface: int PAPI_start_counters( int *events, int array_len ); Parameters: *events an array of codes for events such as PAPI_INT_INS or a native event code array_len the number of items in the *events array Return values: PAPI_EINVAL One or more of the arguments is invalid. PAPI_EISRUN Counters have already been started, you must call PAPI_stop_counters() before you call this function again. PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable. PAPI_ENOMEM Insufficient memory to complete the operation. PAPI_ECNFLCT The underlying counter hardware cannot count this event and other events in the EventSet simultaneously. PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware. PAPI_start_counters() starts counting the events named in the *events array. This function cannot be called if the counters have already been started. The user must call PAPI_stop_counters() to stop the events explicitly if he/she wants to call this function again. It is the user's responsibility to choose events that can be counted simultaneously by reading the vendor's documentation. The length of the *events array should be no longer than the value returned by PAPI_num_counters(). if( PAPI_start_counters( Events, num_hwcntrs ) != PAPI_OK ) handle_error(1); * See Also: PAPI_stop_counters() PAPI_add_event() PAPI_create_eventset() Author Generated automatically by Doxygen for PAPI from the source code.
