PAPI_state(3)							       PAPI							     PAPI_state(3)

NAME

       PAPI_state -

       Return the counting state of an EventSet.

SYNOPSIS

Detailed Description
       C Interface:
	   #include <papi.h>
	    int PAPI_state( int  EventSet, int * status );

       Parameters:
	   EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset
	   status -- an integer containing a boolean combination of one or more of the following nonzero constants as defined in the PAPI header
	   file papi.h:

	   o PAPI_STOPPED -- EventSet is stopped
	   o PAPI_RUNNING -- EventSet is running
	   o PAPI_PAUSED -- EventSet temporarily disabled by the library
	   o PAPI_NOT_INIT -- EventSet defined, but not initialized
	   o PAPI_OVERFLOWING -- EventSet has overflowing enabled
	   o PAPI_PROFILING -- EventSet has profiling enabled
	   o PAPI_MULTIPLEXING -- EventSet has multiplexing enabled
	   o PAPI_ACCUMULATING -- reserved for future use
	   o PAPI_HWPROFILING -- reserved for future use

       Return values:
	   PAPI_OK
	   PAPI_EINVAL One or more of the arguments is invalid.
	   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 %d0,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 %d0,status);
	   *
