Declaration

Source position: blowfish.pp line 76

public function TBlowFishDeCryptStream.Seek(

Offset: LongInt;

Origin: Word

):LongInt; override;

Arguments

`Offset`		Offset. Only zero or positive values allowed.
`Origin`		Origin. Only `soFromCurrent` allowed.

Function result

New position in the stream

Description

Seek emulates a forward seek by reading and discarding data. The discarded data is lost. Since it is a forward seek, this means that only soFromCurrent can be specified for Origin with a positive (or zero) Offset value. All other values will result in an exception. The function returns the new position in the stream.

Errors

If any other combination of Offset and Origin than the allowed combination is specified, then an EBlowFishError exception will be raised.
