PAPIF_get_multiplex(C_INTEventSet,C_INTcheck)ParametersEventSet an integer handle for a PAPI event set as created by PAPI_create_eventsetReturnvaluesPAPI_OKPAPI_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 multiplexing\n.")
if (ret == FALSE) printf("This event set is not enabled for multiplexing\n.")
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 enabled\n");
else if (ret != PAPI_OK) handle_error(ret);
