PAPI_start_counters(3) PAPI PAPI_start_counters(3)
Start counting hardware events.
@par C Interface:
int PAPI_start_counters( int *events, int array_len );
*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
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().
