reclass file?

This function determines if the raster map name in mapset is a reclass file. If it is, then the name and mapset of the referenced raster map are copied into the r_name and r_mapset buffers. Returns 1 if name is a reclass file, 0 if it is not, and -1 if there was a problem reading the raster header for name.

Parameters

name
mapset
r_name
r_mapset

Returns

int

	)

get child reclass maps list

This function generates a child reclass maps list from the cell_misc/reclassed_to file which stores this list. The cell_misc/reclassed_to file is written by G_put_reclass(). G_is_reclassed_to() is used by g.rename, g.remove and r.reclass to prevent accidentally deleting the parent map of a reclassed raster map.

Parameters

name
mapset
nrmaps
rmaps

Returns

int
