NAME

       MPI_T_event_get_info -  Returns additional information about a specific
       event type


SYNOPSIS

       int MPI_T_event_get_info(int event_index, char *name, int *name_len,
       int *verbosity, MPI_Datatype array_of_datatypes[],
       MPI_Aint array_of_displacements[], int *num_elements,
       MPI_T_enum *enumtype, MPI_Info *info, char *desc,
       int *desc_len, int *bind)




INPUT PARAMETERS

       event_index
              - index of the event type to be queried between $0$ and
              $num_events-1$ (integer)



INPUT/OUTPUT PARAMETERS

       name_len
              - length of the string and/or buffer for name (integer)
       num_elements
              - length of array\\_of\\_datatypes and array\\_of\\_displacements
              arrays (non-negative integer)
       desc_len
              - length of the string and/or buffer for desc (integer)



OUTPUT PARAMETERS

       name   - buffer to return the string containing the name of the event
              type (string)
       verbosity
              - verbosity level of this event type (integer)
       array_of_datatypes
              - array of mpi basic datatypes used to encode the event data
              (handle)
       array_of_displacements
              - array of byte displacements of the elements in the event buffer
              (non-negative integer)
       enumtype
              - optional descriptor for enumeration information (handle)
       info   - optional info object (handle)
       desc   - buffer to return the string containing a description of the
              event type (string)
       bind   - type of mpi object to which an event of this type must be bound
              (integer)



THREAD AND INTERRUPT SAFETY

       This routine is thread-safe.  This means that this routine may be safely
       used by multiple threads without the need for any user-provided thread
       locks.  However, the routine is not interrupt safe.  Typically, this is
       due to the use of memory allocation routines such as malloc or other non-
       MPICH runtime routines that are themselves not interrupt-safe.



ERRORS

       All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value;
       C routines as the value of the function and Fortran routines in the last
       argument.  Before the value is returned, the current MPI error handler is
       called.  By default, this error handler aborts the MPI job.  The error
       handler may be changed with MPI_Comm_set_errhandler (for communicators),
       MPI_File_set_errhandler (for files), and MPI_Win_set_errhandler (for RMA
       windows).  The MPI-1 routine MPI_Errhandler_set may be used but its use
       is deprecated.  The predefined error handler MPI_ERRORS_RETURN may be
       used to cause error values to be returned.  Note that MPI does not
       guarantee that an MPI program can continue past an error; however, MPI
       implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_T_ERR_INVALID
              - Invalid use of the interface or bad parameter values(s).
       MPI_T_ERR_INVALID_INDEX
              - Index is invalid or has been deleted.
       MPI_T_ERR_NOT_INITIALIZED
              - The MPI tool information interface is not initialized.
       MPI_ERR_OTHER
              - Other error; use MPI_Error_string to get more information about
              this error code.
