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 ); 
*
