Name

• PAPI_event_code_to_name - convert a numeric hardware event code to a name.
• PAPI_event_name_to_code - convert a name to a numeric hardware event code.

Synopsis

C Interface

#include <papi.h>
int PAPI_event_code_to_name(int  EventCode, char * EventName );
int PAPI_event_name_to_code(char * EventName, int * EventCode );

Fortran Interface

#include fpapi.h
PAPIF_event_code_to_name(C_INT  EventCode,  C_STRING  EventName,  C_INT  check )
PAPIF_event_name_to_code(C_STRING  EventName,  C_INT  EventCode,  C_INT  check )

Description

PAPI_event_code_to_name() is used to translate a 32-bit integer PAPI event code into an ASCII PAPI event name. Either Preset event codes or Native event codes can be passed to this routine. Native event codes and names differ from platform to platform. PAPI_event_name_to_code() is used to translate an ASCII PAPI event name into an integer PAPI event code.

Arguments

EventName -- a string containing the event name as listed in PAPI_presets(3) or discussed in PAPI_native(3)

EventCode -- the numeric code for the event

Errors

PAPI_EINVAL One or more of the arguments is invalid.

PAPI_ENOTPRESET The hardware event specified is not a valid PAPI preset.

PAPI_ENOEVNT The hardware event is not available on the underlying hardware.

Examples

int EventCode, EventSet = PAPI_NULL;
char EventCodeStr[PAPI_MAX_STR_LEN];
char EventDescr[PAPI_MAX_STR_LEN];
char EventLabel[20];
/* Convert to integer */
if (PAPI_event_name_to_code("PAPI_TOT_INS",&EventCode) != PAPI_OK)
handle_error(1);
/* Create the EventSet */
if (PAPI_create_eventset(&EventSet) != PAPI_OK)
handle_error(1);
/* Add Total Instructions Executed to our EventSet */
if (PAPI_add_event(EventSet, EventCode) != PAPI_OK)
handle_error(1);
