Romain,

I have to confess I'm still having problems with getting the point.
AFAIU, you know how to read an existing shapefile.
You read it into an instance of the OGRFeature type.
This object is actually a copy of data from shapefile
and is stored in memory.
Now, AFAIU, you want to modify this object (modify a feature attributes, 
geometry) and write back to shapefile, on the same place, if I am correct.

You can achieve the latter using OGRFeature::SetFeature [1] method.

Does it answer your question?
