NAME

PAPI_assign_eventset_component - Assign a component index to an existing but empty EventSet.

SYNOPSIS

Detailed Description

C Interface:

#include <papi.h>
PAPI_assign_eventset_component( int EventSet, int cidx );

Parameters

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

Return values

PAPI_ENOCMP The argument cidx is not a valid component.
PAPI_ENOEVST The EventSet doesn't exist.
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.

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 );
