Hi,

GetFeatureCount() exists for GDAL users, not for driver writers. For example, in QGIS, you can right-click on a layer, choose "Show Feature Count" and you'll see the number of features next to the layer name.

Or, to give another example, a hypothetical application could use it to display a progress bar during its execution (e.g. "processed 1500 out of 50 000 features").

Hi, here I am again.

Then, after all that information I have the next doubt: for what GetFeatureCount() is used for??

Thanks!
