## Functions

PangoMap * | pango_find_map ()
PangoEngine * | pango_map_get_engine ()

## Description

Functions and macros in this section are used to support loading dynamic modules that add engines to Pango at run time.

## Functions

### pango_find_map ()

    PangoMap *
    pango_find_map (PangoLanguage *language,
                    guint engine_type_id,
                    guint render_type_id);

`pango_find_map` has been deprecated since version 1.38 and should not be used in newly-written code.

Do not use. Does not do anything.

#### Parameters

language | the language tag for which to find the map |
engine_type_id | the engine type for the map to find |
render_type_id | the render type for the map to find |

#### Returns

`NULL`.

### pango_map_get_engine ()

    PangoEngine *
    pango_map_get_engine (PangoMap *map,
                          PangoScript script);

`pango_map_get_engine` has been deprecated since version 1.38 and should not be used in newly-written code.

Do not use. Does not do anything.

[skip]

#### Parameters

map | a PangoMap |
script | a PangoScript |

#### Returns

`NULL`.

### pango_map_get_engines ()

    void
    pango_map_get_engines (PangoMap *map,
                           PangoScript script,
                           GSList **exact_engines,
                           GSList **fallback_engines);

`pango_map_get_engines` has been deprecated since version 1.38 and should not be used in newly-written code.

Do not use. Does not do anything.

[skip]

#### Parameters

map | a PangoMap |
script | a PangoScript |
exact_engines | location to store list of engines that exactly handle this script. |
fallback_engines | location to store list of engines that approximately handle this script. |

Since: 1.4

### pango_module_register ()

    void
    pango_module_register (PangoIncludedModule *module);

`pango_module_register` has been deprecated since version 1.38 and should not be used in newly-written code.

Do not use. Does not do anything.

#### Parameters

module | a PangoIncludedModule |

## Types and Values

### struct PangoIncludedModule

    struct PangoIncludedModule {
      void (*list) (PangoEngineInfo **engines,
    		int              *n_engines);
      void (*init) (GTypeModule      *module);
      void (*exit) (void);
      PangoEngine *(*create) (const char       *id);
    };

`PangoIncludedModule` has been deprecated since version 1.38 and should not be used in newly-written code.

The PangoIncludedModule structure for a statically linked module contains the functions that would otherwise be loaded from a dynamically loaded module.

#### Members

`list` () | a function that lists the engines defined in this module. |
`init` () | a function to initialize the module. |
`exit` () | a function to finalize the module. |
`create` () | a function to create an engine, given the engine name. |

### PangoMap

    typedef struct _PangoMap PangoMap;

### PangoMapEntry

    typedef struct _PangoMapEntry PangoMapEntry;
