PAPI_add_named_event -

add PAPI preset or native hardware event by name to an EventSet

C Interface:

#include <papi.h>
int PAPI_add_named_event( int EventSet, const char *EventName );

PAPI_add_named_event adds one event to a PAPI EventSet.
A hardware event can be either a PAPI preset or a native hardware event code. For a list of PAPI preset events, see PAPI_presets or run the avail test case in the PAPI distribution. PAPI presets can be passed to PAPI_query_event to see if they exist on the underlying architecture. For a list of native events available on current platform, run the papi_native_avail utility in the PAPI distribution.

Parameters:

EventSet An integer handle for a PAPI Event Set as created by PAPI_create_eventset.
EventCode A defined event such as PAPI_TOT_INS.

Return values:

Positive-Integer The number of consecutive elements that succeeded before the error.
PAPI_EINVAL One or more of the arguments is invalid.
PAPI_ENOINIT The PAPI library has not been initialized.
PAPI_ENOMEM Insufficient memory to complete the operation.
PAPI_ENOEVST The event set specified does not exist.
PAPI_EISRUN The event set is currently counting events.
PAPI_ECNFLCT The underlying counter hardware can not count this event and other events in the event set simultaneously.
PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware.
PAPI_EBUG Internal error, please send mail to the developers.
PAPI_EMULPASS Event exists, but cannot be counted due to multiple passes required by hardware.

Examples:

char EventName = "PAPI_TOT_INS";
int EventSet = PAPI_NULL;
unsigned int native = 0x0;
if ( PAPI_create_eventset( &EventSet ) != PAPI_OK )
handle_error( 1 );
// Add Total Instructions Executed to our EventSet
if ( PAPI_add_named_event( EventSet, EventName ) != PAPI_OK )
handle_error( 1 );
// Add native event PM_CYC to EventSet
if ( PAPI_add_named_event( EventSet, "PM_CYC" ) != PAPI_OK )
handle_error( 1 );
