PAPI_add_named_event(3) PAPI PAPI_add_named_event(3)NAMEPAPI_add_named_event-
add PAPI preset or native hardware event by name to an EventSet
SYNOPSISDetailed Description
C Interface:
#include <papi.h>
int PAPI_add_named_event( int EventSet, 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.
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 );
