Romain,

Could you be more specific what you mean as "write data contained in 
OGRDataSource" ?

The tutorial (http://gdal.org/ogr/ogr_apitut.html) presents all 
necessary steps to:
- create datasource and layer for shapefile
- create schema
- write attributes data
- write geometry

If you want to add features to existing shapefile, then open it in 
update mode [1] and create [2] and write [3] new features into it.
