Description

Resets the current position of the handle stream.

System.Classes.TBufferedFileStream.Seek inherits from System.Classes.THandleStream.Seek. All content below this line refers to System.Classes.THandleStream.Seek.

Resets the current position of the handle stream.

Use Seek to move the current position within the resource associated with the handle stream by the indicated offset. Seek allows an application to read from or write to a particular location within the resource.

The Origin parameter indicates how to interpret the Offset parameter. Origin should be one of the following values:

Value	Meaning
soFromBeginning	Offset is from the beginning of the resource. Seek moves to the position Offset. Offset must be >= 0.
soFromCurrent	Offset is from the current position in the resource. Seek moves to Position + Offset.
soFromEnd	Offset is from the end of the resource. Offset must be <= 0 to indicate a number of bytes before the end of the file.

Or you can also use TSeekOrigin and its values to indicate where to start a seek operation.

Seek returns the new value of the Position property, the new current position in the resource.
