Sets the current position in the stream
Source position: line 0
public function TStream.Seek( |
Offset: LongInt; |
Origin: Word |
):LongInt; virtual; overload; |
const Offset: Int64; |
Origin: TSeekOrigin |
):Int64; virtual; overload; |
Seek sets the position of the stream to Offset bytes from Origin. Origin can have one of the following values:
| Constant | Meaning |
| soFromBeginning | Set the position relative to the start of the stream. |
| soFromCurrent | Set the position relative to the beginning of the stream. |
| soFromEnd | Set the position relative to the end of the stream. |
Offset should be negative when the origin is SoFromEnd. It should be positive for soFromBeginning and can have both signs for soFromCurrent
This is an abstract method, which must be overridden by descendent classes. They may choose not to implement this method for all values of Origin and Offset.
An exception may be raised if this method is called with an invalid pair of Offset,Origin values. e.g. a negative offset for soFromBeginning.
