== exception propagation in Ada. ==
In [[Rendezvous#The_task|Ada's Rendezvous]] what do these lines do:
exception
when Out_Of_Ink =>
null;
end;
They look like they are masking/ignoring the ''Out_Of_Ink'' exception.
Whereas program appears to propagate ''Out_Of_Ink'' back to ''Mother_Goose''. e.g.
requeue Backup.Print with abort;
Is that because
Also: when the task is requeued,
waiting for ''Backup'' to finish? (Or is the exception propagated directly
back to ''Mother_Goose'' without passing through ''Backup'')
ThanX
