This is Enumerated type to represent the seeking direction of a stream seeking operation.
The possible values for this type are one of the following member constants as shown below −
|member constant||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 referred to either directly by their name as members of ios_base (like ios_base::beg) or by using any of their inherited classes or instantiated objects, like for example ios::end or cin.cur.
