NAME

       MPI_Type_set_name -  Set a name on a datatype

SYNOPSIS

       #include <mpi.h>
       int
       MPI_Type_set_name(MPI_Datatype type, char *name)

INPUT PARAMETERS

       type   - MPI datatype
       name   - Pointer to the name of dataname

NOTES

       This  function  associates  a  name  with  a  datatype,  which can be useful for debugging
       purposes.  The function MPI_Type_get_name can be used to retrieve name that was previously
       set with MPI_Type_set_name .

       Named  predefined  datatypes  have  the  default  names of the datatype name. For example,
       MPI_WCHAR has the default name of MPI_WCHAR .

       It is legal to change any of these names with calls to MPI_Type_set_name .

       Names passed in C must  include  the  null  terminator,  and  can  be  of  maximum  length
       MPI_MAX_OBJECT_NAME  (including  the  null  terminator).  Names passed in Fortran can also
       have a maximum length of MPI_MAX_OBJECT_NAME .

       Setting a name on a datatype that already has a name associated with it replaces  the  old
       name.

ERRORS

       If  an  error occurs in an MPI function, the current MPI error handler is called to handle
       it.  By default, this error handler aborts the MPI job.  The error handler may be  changed
       with  MPI_Errhandler_set  ;  the predefined error handler MPI_ERRORS_RETURN may be used to
       cause error values to be returned (in C and Fortran; this error handler is less useful  in
       with  the  C++  MPI  bindings.   The predefined error handler MPI::ERRORS_THROW_EXCEPTIONS
       should be used in C++ if the error value needs to be recovered).  Note that MPI  does  not
       guarantee that an MPI program can continue past an error.

       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.  The C++ bindings for
       MPI  do  not  return  error  values;  instead,  error  values are communicated by throwing
       exceptions of type MPI::Exception (but not by default).  Exceptions are only thrown if the
       error value is not MPI::SUCCESS .

       Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return
       upon an error, there will be no way to recover what the actual error value was.
       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_TYPE
              -  Invalid  datatype  argument.   May   be   an   uncommitted   MPI_Datatype   (see
              MPI_Type_commit ).
       MPI_ERR_ARG
              -  Invalid  argument.  Some argument is invalid and is not identified by a specific
              error class.  This is typically a NULL pointer or other such error.
