What does the word "TBD" means in mpi_get_processor_name function

Question

I was reading the documentation reference about MPI function: MPI_Get_processor_name(...) in Microsoft's docs. https://msdn.microsoft.com/en-us/library/dn473382(v=vs.85).aspx

And I found The word "TBD" replaces every Explanation to be expected about the purpose of the function or the parameters.

Does it mean "To Be Deleted" or "To Be Defined" or ... ? Thx in advance;
