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.
