NAME

       PAPI_get_multiplex - Get the multiplexing status of specified event set.

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\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);
