NAME
PAPI_remove_named_event - removes a named hardware event from a PAPI event set.
SYNOPSIS
Detailed Description
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 papi_avail utility 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 the current platform, run papi_native_avail in the PAPI distribution.
C Interface:
#include <
papi.h
>
int
PAPI_remove_named_event( int EventSet, const char
*EventName )
;
Parameters
EventSet
-- an integer
handle for a PAPI event set as created by
PAPI_create_eventset
EventName
-- a defined event such as PAPI_TOT_INS or a
native event.
Return values
PAPI_OK
Everything
worked.
PAPI_EINVAL
One or more of the arguments is invalid.
PAPI_ENOINIT
The PAPI library has not been initialized.
PAPI_ENOEVST
The EventSet specified does not exist.
PAPI_EISRUN
The EventSet is currently counting events.
PAPI_ECNFLCT
The underlying counter hardware can not
count this event and other events in the EventSet
simultaneously.
PAPI_ENOEVNT
The PAPI preset is not available on the
underlying hardware.
Example:
char EventName
= "PAPI_TOT_INS";
int EventSet = PAPI_NULL;
int ret;
// Create an
empty EventSet
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
// Add Total
Instructions Executed to our EventSet
ret = PAPI_add_named_event(EventSet, EventName);
if (ret != PAPI_OK) handle_error(ret);
// Start
counting
ret = PAPI_start(EventSet);
if (ret != PAPI_OK) handle_error(ret);
// Stop
counting, ignore values
ret = PAPI_stop(EventSet, NULL);
if (ret != PAPI_OK) handle_error(ret);
// Remove event
ret = PAPI_remove_named_event(EventSet, EventName);
if (ret != PAPI_OK) handle_error(ret);
