Vector library - write vector feature - simple feature access (level 2)
Higher level functions for reading/writing/manipulating vectors.
See write_ogr.c (OGR interface) and write_pg.c (PostGIS interface) for imlementation issues.
SFA version of V2__delete_area_cats_from_cidx_nat()
function to delete corresponding entry in fidx
SFA version of V2__add_area_cats_to_cidx_nat
SFA version of V2__add_line_to_topo_nat
