    Declaration

    Source position: bufstream.pp line 137

    public 
function Seek(Offset: LongInt; Origin: Word) : LongInt;  override
             ;  overload; overload;

function Seek(const Offset: Int64; Origin: TSeekOrigin) : Int64
             ;  override;  overload; overload;

    Description

    Seek is a method used to change the current position in the buffered file stream by the number of bytes in Offset relative to the given Origin. Overloaded variants are provided which use LongInt or Int64 types for the Offset parameter, and Word or TSeekOrigin types for the Origin parameter.

    Seek is overridden to use the size and position in the internal buffer when positioning the buffered file stream.

    The return value contains the actual number of bytes the position was moved relative to the Origin. As with TStream, the return value may contain -1 if the stream position was not moved.
