PAPI_create_eventset -

Create a new empty PAPI EventSet.


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 );
