I once did a Terminal_IO package  (with procedures like
Put_At (Row,Col, Text)) where the underlying system calls
were functions that always returned a success/error status.
Since this is not usually interesting, I introduced a body-global
status flag and a function in the Terminal_IO package spec,
Get_Last_Status. That way I could turn the Terminal_IO
user level functions into procedures, and one could call
Get_Last_Status for finding out the status of the last call if
need be.
