SYNOPSIS
C Interface
#include <papi.h>
int PAPI_rem_event(int *EventSet, int EventCode);
int PAPI_rem_events(int *EventSet, int *EventCode, int number);
int PAPI_rem_pevent(int *EventSet, int code, void * misc);
Fortran Interface
#include fpapi.h
PAPIF_rem_event(C_INT EventSet, C_INT EventCode, C_INT check)
PAPIF_rem_events(C_INT EventSet, C_INT(*) EventCode, C_INT number, C_INT check)
DESCRIPTION
PAPI_rem_event() removes a hardware event to a PAPI event set.
PAPI_rem_events() does the same, but for an array of hardware event codes.
PAPI_rem_pevent() is reserved for future use.
ARGUMENTS
EventSet -- an integer handle for a PAPI event set as created by
PAPI_create_eventset (3)
EventCode -- a defined event such as PAPI_TOT_INS or a native event.
*EventCode -- an array of defined events
number -- an integer indicating the number of events in the array
*EventCode
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 (3) or run the
avail test case in the PAPI distribution. PAPI Presets can be passed to
PAPI_query_event (3) to see if they exist on the underlying architecture.
For the encoding of native events, see the <arch>.README file
also included the distribution.
RETURN VALUES
On success, this function returns
PAPI_OK.
On error, a non-zero error code is returned.
ERRORS
|
PAPI_EINVAL | | |
One or more of the arguments is invalid.
|
|
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.

EXAMPLES
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_event(&EventSet, PAPI_TOT_INS) != PAPI_OK)
handle_error(1);
/* Start counting */
if (PAPI_start(EventSet) != PAPI_OK)
handle_error(1);
/* Stop counting, ignore values */
if (PAPI_stop(EventSet, NULL) != PAPI_OK)
handle_error(1);
/* Remove event */
if (PAPI_rem_event(&EventSet, PAPI_TOT_INS) != PAPI_OK)
handle_error(1);
