Functions | |
void | fatal_error (int ferror, char *errmsg) |
int | Vect_set_open_level (int level) |
Predetermine level at which a map will be opened for reading. If it can't open that level, the open will fail. The specified level must be set before any call to open. The default is to try to open the highest level possible, and keep stepping down until success. | |
int | Vect__open_old (struct Map_info *Map, char *name, char *mapset, int update, int head_only) |
Returns Level of openness. [ 1, 2 ] or -1 for error. In case of error, the functions respect fatal error settings. | |
int | Vect_open_old (struct Map_info *Map, char *name, char *mapset) |
Open old vector for reading. | |
int | Vect_open_update (struct Map_info *Map, char *name, char *mapset) |
Open old vector for reading/writing. | |
int | Vect_open_old_head (struct Map_info *Map, char *name, char *mapset) |
Reads only info about vector from headers of 'head', 'dbln', 'topo' and 'cidx' file. | |
int | Vect_open_update_head (struct Map_info *Map, char *name, char *mapset) |
Open old vector head for updating (mostly for database link updates). | |
int | Vect_open_new (struct Map_info *Map, char *name, int with_z) |
Open new vector for reading/writing. | |
int | Vect_coor_info (struct Map_info *Map, struct Coor_info *Info) |
ADD. | |
char * | Vect_maptype_info (struct Map_info *Map) |
returns maptype (native, shape, postgis) | |
int | Vect_open_topo (struct Map_info *Map, int head_only) |
int | Vect_open_spatial_index (struct Map_info *Map) |
Open spatial index file. |

int Vect_set_open_level | ( | int | level | ) |
Predetermine level at which a map will be opened for reading. If it can't open that level, the open will fail. The specified level must be set before any call to open. The default is to try to open the highest level possible, and keep stepping down until success.
NOTE!! This should only be used to set when you wish to force a lower level open. If you require a higher level, then just check the return to verify the level instead of forcing it. This is because future releases will have higher levels which will be downward compatible and which your programs should support by default.
