[Qgis-developer] qgis vector editing/digitisation

Yes, it is possible (but the application needs to be licensed under the terms 
of GPL).

Basically the class QgsVectorLayer (qgsvectorlayer.h). This class caches the 
edits in memory and commits changes to the providers.

You need the core library (libqgiscore.so) and probably also the gui library 
for display.

You could look at the edit tool classes (e.g. qgsmaptooladdfeature.cpp/h, 
qgsmaptoolsplitfeatures.cpp/h).
