You might want to look into Starspan
<http://starspan.casil.ucdavis.edu/>. It will perform various raster
statistics based on vectors and output the results to csv. It does not
yet append the results to the vector attribute table but this can
accomplished by joining the csv to the original shapfile (using a
desktop GIS, Postgres/postgis database or through the OGR libs)

Starspan is written in C++ and used the GDAL and GEOS libraries so it
might also serve as a good example to get started with.
