Description

Seek sets the location in the buffer. Currently, only a forward seek is allowed. It is emulated by reading and discarding data. For an explanation of the parameters, see TStream.Seek"

The seek method needs enhancement to enable it to do a full-featured seek. This may be implemented in a future release of Free Pascal.

Errors

In case an illegal seek operation is attempted, an exception is raised.
