Description
WriteMarker is a procedure used to write the specified marker to the internal stream for the in-memory dataset. Markers are used to separate field definitions from the record data in the stream. A marker is also used to indicate the end of the stream. WriteMarker is used in methods which write the content for the in-memory dataset, such as: SaveToStream, SaveFieldDefsToStream, and SaveDataToStream.
Marker contains one of the predefined marker constants: smFieldDefs, smData, or smEOF. WriteMarker writes the value in Marker to to the stream in F.
