    TInputPipeStream.Seek

    Set the current position of the stream.

    Declaration

    Source position: pipes.pp line 47

    public 
function TInputPipeStream.Seek(const Offset: Int64; Origin: TSeekOrigin)
                               : Int64;  override;

    Description

    Seek overrides the standard Seek implementation. Normally, pipe streams stderr are not seekable. The TInputPipeStream stream tries to provide seek capabilities for the following limited number of cases:

    Origin=soFromBeginning
    If Offset is larger than the current position, then the remaining bytes are skipped by reading them from the stream and discarding them.
    Origin=soFromCurrent
    If Offset is zero, the current position is returned. If it is positive, then Offset bytes are skipped by reading them from the stream and discarding them, if the stream is of type iosInput.

    All other cases will result in a EPipeSeek exception.

    Errors

    An EPipeSeek exception is raised if the stream does not allow the requested seek operation.
