.br

\fIPAPI_EINVAL\fP One or more of the arguments is invalid\&. 

.br

\fIPAPI_ESYS\fP A system or C library call failed inside PAPI, see the errno variable\&.

\fBPAPI_stop\fP halts the counting of a previously defined event set and the counter values contained in that EventSet are copied into the values array Assumes an initialized PAPI library and a properly added event set\&.

.nf

*  int EventSet = PAPI_NULL;

*  long long values[2];

*  int ret;

*  

*  ret = PAPI_create_eventset(&EventSet);

*  // 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);
