NAME

       PAPI_assign_eventset_component -

       Assign a component index to an existing but empty EventSet.

SYNOPSIS

Detailed Description
       @par C Interface:
       PAPI_assign_eventset_component( int  EventSet, int  cidx );

       @param EventSet
	   An integer identifier for an existing EventSet.
       @param cidx
	   An integer identifier for a component.
	   By convention, component 0 is always the cpu component.

       @retval PAPI_ENOCMP
	   The argument cidx is not a valid component.
       @retval PAPI_ENOEVST
	   The EventSet doesn't exist.
       @retval PAPI_ENOMEM
	   Insufficient memory to complete the operation.

       PAPI_assign_eventset_component assigns a specific component index,
       as specified by cidx, to a new EventSet identified by EventSet, as obtained
       from PAPI_create_eventset. EventSets are ordinarily automatically bound
       to components when the first event is added. This routine is useful to
       explicitly bind an EventSet to a component before setting component related
       options.

       @par Examples:

       *   int EventSet = PAPI_NULL;
       *   if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Bind our EventSet to the cpu component
       *   if ( PAPI_assign_eventset_component( EventSet, 0 ) != PAPI_OK )
       *   handle_error( 1 );
       *   // Convert our EventSet to multiplexing
       *   if ( PAPI_set_multiplex( EventSet ) != 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);
	   *
