Gets the .minimum component value of `datatype`

`datatype` : | FoLengthRange
Returns : | The .minimum value of `datatype`

### fo_length_range_get_optimum ()

    FoDatatype* fo_length_range_get_optimum     (FoDatatype *datatype);

Gets the .optimum component value of `datatype`

`datatype` : | FoLengthRange
Returns : | The .optimum value of `datatype`

### fo_length_range_get_maximum ()

    FoDatatype* fo_length_range_get_maximum     (FoDatatype *datatype);

Gets the .maximum component value of `datatype`

`datatype` : | FoLengthRange
Returns : | The .maximum value of `datatype`

### fo_length_range_resolve ()

    FoDatatype* fo_length_range_resolve         (FoDatatype *shortform,
                                                 FoDatatype *minimum,
                                                 FoDatatype *optimum,
                                                 FoDatatype *maximum,
                                                 gfloat hundred_percent,
                                                 GError **error);

Resolve the shortform and components of the length-range in accordance with Section 5.11, Datatypes, of the XSL 1.0 Recommendation.

Does not change the ref-count of any FoDatatype arguments.

`shortform` : | Single-value short form of the length-range, or NULL
`minimum` : | .minimum component of the length-range, or NULL
`optimum` : | .optimum component of the length-range, or NULL
`maximum` : | .maximum component of the length-range, or NULL
`hundred_percent` : | Length to use as 100% when components expressed as percentages
`error` : | GError used for reporting errors
Returns : | Compound length-range datatype, or NULL if an error occurred

### fo_length_range_resolve_allow_auto ()

    FoDatatype* fo_length_range_resolve_allow_auto
                                                (FoDatatype *shortform,
                                                 FoDatatype *minimum,

                                                 GError **error);

Resolve the shortform and components of the length-range in accordance with the definitions of block-progression-dimension and inline-progression-dimension in Section 7.14, Area Dimension Properties, of the XSL 1.0 Recommendation.

Use this when "auto" is an allowed value and percentages are computed into lengths.

Does not change the ref-count of any FoDatatype arguments.

`shortform` : | Single-value short form of the length-range, or NULL
`minimum` : | .minimum component of the length-range, or NULL
`optimum` : | .optimum component of the length-range, or NULL

`hundred_percent` : | Length to use as 100% when components expressed as percentages
`error` : | GError used for reporting errors
Returns : | Compound length-range datatype, or NULL if an error occurred

### fo_length_range_get_length_range_hundred_percent ()
