Seek

Declaration:

TFileStream.Seek (Offset: longint; Origin: word): longint;

The method Seek moves the stream Position in the file stream to the value Offset. Offset is interpreted differently, depending on the value of Origin: soFromBeginning Offset is from the beginning of the resource. Seek moves to the position Position. Offset must be >= 0. soFromCurrent Offset is from the current position in the resource. Seek moves to Position + Position. soFromEnd Offset is from the end of the resource. Position must be <= 0 to indicate a number of bytes before the end of the file. Seek returns the new value of the Position property.
