Detailed Description

Vector library - Building topology for OGR.

Higher level functions for reading/writing/manipulating vectors.

Category: FID, not all layer have FID, OGRNullFID is defined (5/2004) as -1, so FID should be only >= 0

This program is free software under the GNU General Public License (>=v2). Read the file COPYING that comes with GRASS for details.

Function Documentation

◆ Vect_build_ogr()

int Vect_build_ogr	(	struct Map_info *	Map,
		int	build
	)

GV_BUILD_BASE
GV_BUILD_ATTACH_ISLES
GV_BUILD_CENTROIDS
GV_BUILD_ALL

Parameters

Map	pointer to Map_info structure
build	build level

Returns: 1 on success; 0 on error

◆ Vect_save_fidx()

int Vect_save_fidx	(	struct Map_info *	Map,
		struct Format_info_offset *	offset
	)

Save feature index file for vector map.

Parameters

Map	pointer to Map_info structure
offset	pointer to Format_info_offset struct (see Format_info_ogr and Format_info_pg struct for implementation issues)

Returns: 1 on success; 0 on error
