NAME

       PAPI_create_eventset -

       Create a new empty PAPI EventSet.

SYNOPSIS

Detailed Description
       @par C Interface:
       PAPI_create_eventset( int * EventSet );

       PAPI_create_eventset creates a new EventSet pointed to by EventSet,
       which must be initialized to PAPI_NULL before calling this routine.
       The user may then add hardware events to the event set by calling
       PAPI_add_event or similar routines.

       @note PAPI-C uses a late binding model to bind EventSets to components.
       When an EventSet is first created it is not bound to a component.
       This will cause some API calls that modify EventSet options to fail.
       An EventSet can be bound to a component explicitly by calling
       PAPI_assign_eventset_component or implicitly by calling PAPI_add_event
       or similar routines.

       @param *EventSet
	   Address of an integer location to store the new EventSet handle.

       @exception PAPI_EINVAL
	   The argument handle has not been initialized to PAPI_NULL or the argument is a NULL pointer.

       @exception PAPI_ENOMEM
	   Insufficient memory to complete the operation.

       @par Examples:

       *   int EventSet = PAPI_NULL;
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Add Total Instructions Executed to our EventSet
       *   if ( PAPI_add_event( EventSet, PAPI_TOT_INS)  != PAPI_OK )
       *   handle_error( 1 );
       *

NAME

       PAPI_set_multiplex -

       Convert a standard event set to a multiplexed event set.

SYNOPSIS

Detailed Description
       C Interface:
	   #include <papi.h>
	    int PAPI_set_multiplex( int  EventSet );

       Parameters:
	   EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset

       Return values:
	   PAPI_OK
	   PAPI_EINVAL -- One or more of the arguments is invalid, or the EventSet is already multiplexed.
	   PAPI_ENOCMP -- The EventSet specified is not yet bound to a component.
	   PAPI_ENOEVST -- The EventSet specified does not exist.
	   PAPI_EISRUN -- The EventSet is currently counting events.
	   PAPI_ENOMEM -- Insufficient memory to complete the operation.

       PAPI_set_multiplex converts a standard PAPI event set created by a call to PAPI_create_eventset into an event set capable of handling
       multiplexed events. This must be done after calling PAPI_multiplex_init, and either PAPI_add_event or PAPI_assign_eventset_component, but
       prior to calling PAPI_start().

       Events can be added to an event set either before or after converting it into a multiplexed set, but the conversion must be done prior to
       using it as a multiplexed set.

       Note:
	   Multiplexing can't be enabled until PAPI knows which component is targeted. Due to the late binding nature of PAPI event sets, this
	   only happens after adding an event to an event set or explicitly binding the component with a call to PAPI_assign_eventset_component.

       Example:

	   *   int EventSet = PAPI_NULL;
	   *   int ret;
	   *
	   *   // Create an empty EventSet
	   *   ret = PAPI_create_eventset(&EventSet);
	   *   if (ret != PAPI_OK) handle_error(ret);
	   *
	   *   // Bind it to the CPU component
	   *   ret = PAPI_assign_eventset_component(EventSet, 0);
	   *   if (ret != PAPI_OK) handle_error(ret);
	   *
	   *   // Check  current multiplex status
	   *   ret = PAPI_get_multiplex(EventSet);
	   *   if (ret == TRUE) printf("This event set is ready for multiplexing.")
	   *   if (ret == FALSE) printf("This event set is not enabled for multiplexing.")
	   *   if (ret < 0) handle_error(ret);
	   *
	   *   // Turn on multiplexing
	   *   ret = PAPI_set_multiplex(EventSet);
	   *   if ((ret == PAPI_EINVAL) && (PAPI_get_multiplex(EventSet) == TRUE))
	   *	 printf("This event set already has multiplexing enabled0);
	   *   else if (ret != PAPI_OK) handle_error(ret);
	   *
