<pre class="fragment">Hello List,
I could probably figure it out from the source, but I would apprecaite
if someone could point me in the right direction.
The question is: does GDAL / OGR loads the file in the memory when it
opens in or it just keeps reference to the actual file
Say if I open it, process it etc
hDS = <a class="code" href="http://www.gdal.org/ogr/ogr__api_8h.html#123bb02ac8c5cfe143e132f627531125" title="Open a file / data source with one of the registered drivers.">OGROpen</a>( <span class="stringliteral">"point.shp"</span>, FALSE, NULL );
....
and then do (without closing)
poLayer-><a class="code" href="http://www.gdal.org/ogr/classOGRLayer.html#ad0f2cd7f0587584b8f382c6a913583c" title="Reset feature reading to start on the first feature.">ResetReading</a>();
and process again
would it actually trigger re-reading file from the disk or not?
In other words does OGR creates complete memory image for the file or
just reads actual file when it needs something?
Thank you
Mikhail
