reclass file?

This function determines if the raster file name in mapset is a reclass file. If it is, then the name and mapset of the referenced raster file 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

int G_is_reclassed_to	(	char *	name,

		int *	nrmaps,
		char ***	rmaps
	)

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
