    Notes:
    The string must be no more than 'MPI_MAX_ERROR_STRING' characters long.
    The length of the string is as defined in the calling language.
    The length of the string does not include the null terminator in C or C++.
    Note that the string is 'const' even though the MPI standard does not
    specify it that way.

    According to the MPI-2 standard, it is erroneous to call 'MPI_Add_error_string'
    for an error code or class with a value less than or equal
    to 'MPI_ERR_LASTCODE'.  Thus, you cannot replace the predefined error messages
    with this routine.

    Notes:
    The MPI Standard states that an implementation may make the output value

    'MPI_Errhandler_free' makes this impossible, since it is required to set the
    value of the argument to 'MPI_ERRHANDLER_NULL'.  In addition, the actual
    error handler must remain until all communicators that use it are
    freed.

    Note on Implementation:

    The MPI Standard was unclear on whether this routine required the user to call
    'MPI_Errhandler_free' once for each call made to this routine in order to
    free the error handler.  After some debate, the MPI Forum added an explicit
    statement that users are required to call 'MPI_Errhandler_free' when the
    return value from this routine is no longer needed.  This behavior is similar
    to the other MPI routines for getting objects; for example, 'MPI_Comm_group'
    requires that the user call 'MPI_Group_free' when the group returned
    by 'MPI_Comm_group' is no longer needed.
