Converts all polygons in a topology to closed polylines.
int
map_topoclose(
char *topoName,
char *layer,
int group,
int odata,
int aselink,
ads_name ssreturn);
Returns RTNORM or RTERROR.
| toponame | The name of a topology. The topology must be closed. |
| layer | The name of the layer that will contain the closed polylines. If the layer name is incorrect (for example "@@"), polylines are created on the current layer. |
| group | Group flag for complex polygons: 1 or 0. 1 group complex polygons 0 do not group complex polygons |
| odata | Object data flag that sets whether to copy object data on the polygon centroid to the resulting polyline: 1 or 0. 1 copy object data on the centroid 0 ignore object data on the centroid |
| aselink | ASE link flag that sets whether to copy ASE link data on the centroid to the resulting polyline: 1 or 0. 1 copy ASE link data on the centroid 0 ignore ASE link data on the centroid |
| ssreturn | The returned selection set containing the closed polylines. |
This function passes the selection set through the ssreturn parameter. If the function returns RTNORM, you must release the returned selection set with the ads_ssfree function.
