NAME

PAPI_create_eventset - Create a new empty PAPI EventSet.

SYNOPSIS

Detailed Description

C Interface:

#include <papi.h>
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.

Parameters:

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

Exceptions:

PAPI_EINVAL The argument handle has not been initialized to PAPI_NULL or the argument is a NULL pointer.
PAPI_ENOMEM Insufficient memory to complete the operation.

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 );
