<p>The CSV driver is actually not that simple to follow since it has tricks to support updates through the OGREditableLayer mechanism. The GMT one (ogr/ogrsf_frmts/gmt) might be a better start for a creation & append only driver. But basically, the only common
thing with your own code will be the fact that you have to implement the 2 virtual methods of interest: OGRLayer::CreateField() ,d OGRLayer::ICreateFeature() and declare a few capabilities in OGRLayer::TestCapability()<o:p></o:p></p>
<p>Unless you want to implement update capabilities (if the format allows it, which is generally not the case for a text based format), it might be simpler to have 2 distinct OGRLayer sub-classes for read-only and write-only operations.<o:p></o:p></p>
