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.
