[mpiwg-tools] Question on ticket 377

[Junchao Zhang]

Hi,
  From the agenda, it seems all tickets for voting at the March meeting are
tools.
  I have a question about ticket
377<https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/377>,
which adds an error code "MPI_T_ERR_INVALID_NAME -- The variable or
category name is invalid".  Remember we also use the word in the other case
like "The variable index is invalid".  So, what is the meaning of invalid
in these two cases?
  I raise this question because in the text we have "When a variable
becomes inactive, e.g., through dynamic unloading, accessing its value
should return a corresponding error code."  Then, what operations are
thought as "accessing its values". Instead of *var_read, can I get_info of
an inactive variable? The answer will affect the definition of "invalid" in
cases above.  So, I think we'd better clarify that.
