 * \brief Read floating-point range

 * written in binary using XDR format.
 *
 * An empty range file indicates that the min, max are undefined. This
 * is a valid case, and the result should be an initialized range
 * struct with no defined min/max.  If the range file is missing and
 * the map is a floating-point map, this function will create a
 * default range by calling G_construct_default_range().

/*!
 * \brief Read raster range (CELL)
 *
 * This routine reads the range information for the raster map
 * <i>name</i> in <i>mapset</i> into the <i>range</i> structure.
 *
 * A diagnostic message is printed and -1 is returned if there is an error
 * reading the range file. Otherwise, 0 is returned.
 *
 * Old range file (those with 4 numbers) should treat zeros in this
 * file as NULL-values. New range files (those with just 2 numbers)
 * should treat these numbers as real data (zeros are real data in
 * this case).  An empty range file indicates that the min, max are
 * undefined. This is a valid case, and the result should be an
 * initialized range struct with no defined min/max. If the range file
 * is missing and the map is a floating-point map, this function will
 * create a default range by calling G_construct_default_range().
 *
 * \param name map name
 * \param mapset mapset name
 * \param[out] range pointer to Range structure which holds range info
 *
 * \return -1 on error
 * \return 1 on success
 * \return 2 if range is empty
 * \return 3 if raster map is floating-point, get range from quant rules
