<div>The text for the errata is:</div>
<div><p> page 568, line 31 add: Any output parameter to MPI_T_cvar_get_info can have a NULL value. In this case, the implementation will ignore the parameter and not return a value for that parameter.
</p><p>page 576, line 46 add: Any output parameter to MPI_T_pvar_get_info can have a NULL value. In this case, the implementation will ignore the parameter and not return a value for that parameter.
</p><p>page 586, line 22 add: Any output parameter to MPI_T_category_get_info can have a NULL value. In this case, the implementation will ignore the parameter and not return a value for that parameter.</p><p>You can see the evolution of this change here:</p>

<div>Hello,</div>
<div> 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. </div>
<div> 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.</div>
