#### FT_PropertyType
      typedef enum  BDF_PropertyType_
      {
        BDF_PROPERTY_TYPE_NONE     = 0,
        BDF_PROPERTY_TYPE_ATOM     = 1,
        BDF_PROPERTY_TYPE_INTEGER  = 2,
        BDF_PROPERTY_TYPE_CARDINAL = 3

      } BDF_PropertyType;
A list of BDF property types.
values
BDF_PROPERTY_TYPE_NONE | Value 0 is used to indicate a missing property.
BDF_PROPERTY_TYPE_ATOM | Property is a string atom.
BDF_PROPERTY_TYPE_INTEGER
| Property is a 32-bit signed integer.
BDF_PROPERTY_TYPE_CARDINAL
| Property is a 32-bit unsigned integer.

#### BDF_PropertyRec
      typedef struct  BDF_PropertyRec_
      {
        BDF_PropertyType  type;
        union {
          const char*     atom;
          FT_Int32        integer;
          FT_UInt32       cardinal;

        } u;

      } BDF_PropertyRec;
This structure models a given BDF/PCF property.
fields
type | The property type.
u.atom | The atom string, if type is BDF_PROPERTY_TYPE_ATOM.
u.integer | A signed integer, if type is BDF_PROPERTY_TYPE_INTEGER.
u.cardinal | An unsigned integer, if type is BDF_PROPERTY_TYPE_CARDINAL.

#### FT_Get_BDF_Charset_ID
      FT_EXPORT( FT_Error )
      FT_Get_BDF_Charset_ID( FT_Face       face,
                             const char*  *acharset_encoding,
                             const char*  *acharset_registry );
Retrieves a BDF font character set identity, according to the BDF specification.
input
face | A handle to the input face.
output
acharset_encoding | Charset encoding, as a C string, owned by the face.
acharset_registry | Charset registry, as a C string, owned by the face.
return
FreeType error code. 0 means success.
note
This function only works with BDF faces, returning an error otherwise.

#### FT_Get_BDF_Property
      FT_EXPORT( FT_Error )
      FT_Get_BDF_Property( FT_Face           face,
                           const char*       prop_name,
                           BDF_PropertyRec  *aproperty );
Retrieves a BDF property from a BDF or PCF font file.
input
face | A handle to the input face.
name | The property name.
output
aproperty | The property.
return
FreeType error code. 0 means success.
note
This function works with BDF and PCF fonts. It returns an error otherwise. It also returns an error if the property is not in the font. In case of error, ‘aproperty->type’ is always set to BDF_PROPERTY_TYPE_NONE.
