PAPI_get_multiplex(3) PAPI PAPI_get_multiplex(3)NAMEPAPI_get_multiplex-
Get the multiplexing status of specified event set.
SYNOPSISDetailed Description
C Interface:
#include <papi.h>
int PAPI_get_multiplex( int EventSet );
Fortran Interface:
#include fpapi.h
PAPIF_get_multiplex( C_INT EventSet, C_INT check )
Parameters:
EventSet an integer handle for a PAPI event set as created by
PAPI_create_eventset
Return values:
PAPI_OK
PAPI_EINVAL One or more of the arguments is invalid, or the
EventSet is already multiplexed.
PAPI_ENOEVST The EventSet specified does not exist.
PAPI_EISRUN The EventSet is currently counting events.
PAPI_ENOMEM Insufficient memory to complete the operation.
PAPI_get_multiplex tests the state of the PAPI_MULTIPLEXING flag in the
specified event set, returning TRUE if a PAPI event set is multiplexed,
or FALSE if not.
Example:
int EventSet = PAPI_NULL;
int ret;
// Create an empty EventSet
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
// Bind it to the CPU component
ret = PAPI_assign_eventset_component(EventSet, 0);
if (ret != PAPI_OK) handle_error(ret);
// Check current multiplex status
ret = PAPI_get_multiplex(EventSet);
if (ret == TRUE) printf('This event set is ready for multiplexing0')
if (ret == FALSE) printf('This event set is not enabled for multiplexing0')
if (ret < 0) handle_error(ret);
// Turn on multiplexing
ret = PAPI_set_multiplex(EventSet);
if ((ret == PAPI_EINVAL) && (PAPI_get_multiplex(EventSet) == TRUE))
printf('This event set already has multiplexing enabled0);
else if (ret != PAPI_OK) handle_error(ret);
