[GRASS-dev] wxvdigit

[Benjamin Ducke]

Generally, you can use C libraries from C++:
http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html

Then look here, and read the sections on the GRASS
vector architecture and the VEdit library:
http://grass.osgeo.org/programming6/

You will find there is quite a lot of functionality in there
already.

The rest is up to your creativity.
