public member type

Type for stream seeking direction flag

Enumerated type to represent the seeking direction of a stream seeking operation.

The possible values for this type are one the following member constants:

flag value	seeking relative to
beg	beginning of sequence.
cur	current position within sequence.
end	end of sequence.

These constants are defined in the ios_base class as public members. Therefore, they can be refered to either directly by their name as ios_base members (like ios_base::beg) or by using any of their inherited classes or instantiated objects, like for example ios::end or cin.cur.
