PAPI_assign_eventset_component -

Assign a component index to an existing but empty EventSet.


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 );
