You can see the evolution of this change here:
_______________________________________________Hello,For function "int MPI_T_pvar_get_info(int pvar_index, char *name, int *name_len, int *verbosity, int *var_class, ...)", MPI_T defines semantics when name or name_len are NULL.But for other args, if they are NULL, is it a user program error or should we just ignore it? I prefer the latter. But the standard doesn't say it.
