SYNOPSIS
Detailed 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 multiplexing&.") * if (ret == FALSE) printf("This event set is not enabled for multiplexing&.") * 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); * else if (ret != PAPI_OK) handle_error(ret); *
