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,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,status);
