PAPI_ENOEVST	The EventSet specified does not exist.

PAPI_state() returns the counting state of the specified event set.

Example:

int EventSet = PAPI_NULL;
int status = 0;
int ret;

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_state(EventSet, &status);
if (ret != PAPI_OK) handle_error(ret);
printf("State is now %d\n",status);
ret = PAPI_start(EventSet);
if (ret != PAPI_OK) handle_error(ret);
ret = PAPI_state(EventSet, &status);
if (ret != PAPI_OK) handle_error(ret);
printf("State is now %d\n",status);
