Get a list of importers. If `target` is supplied, then only importers which support the type and location specified by the target are listed. If `target` is NULL, then all importers are listed.

#### Parameters

import | an EImport |
target | an EImportTarget |

A list of importers. The list should be freed when no longer needed.

id | The name of the instance. |

#### Returns

`ep` is returned.

                     gpointer data);

Run the import function of the selected importer. Once the importer has finished, it MUST call the `e_import_complete()` function. This allows importers to run in synchronous or asynchronous mode.

When complete, the `done` callback will be called.

#### Parameters

import | an EImport |
target | Target to import. |
importer | Importer to use. |
status | Status callback, called with progress information. |
done | Complete callback, will always be called once complete. |
data | user data for callback functions |

                         EImportImporter *importer);

Gets a widget that the importer uses to configure its destination. This widget should be packed into a container widget. It should not be shown_all.

#### Parameters

import | an EImport |
target | Target of interest |
importer | Importer to get widget of |

#### Returns

NULL if the importer doesn't support/require a destination.

### e_import_get_preview_widget ()

    GtkWidget *
    e_import_get_preview_widget (EImport *import,
                                 EImportTarget *target,
                                 EImportImporter *im);

Gets a widget that the importer uses to preview data to be imported. This widget should be packed into a container widget. It should not be shown_all.

#### Parameters

import | an EImport |
target | Target of interest |
im | Importer to get a preview widget of |

#### Returns

NULL if the importer doesn't support preview.

### e_import_status ()

    e_import_complete (EImport *import,
                       EImportTarget *target);

Signify that an import is complete. This must be called by importer implementations when they are done.

#### Parameters

import | an EImport |
target | Target just completed (unused currently) |

### e_import_target_new ()

    gpointer
    e_import_target_new (EImport *import,
                         gint type,
                         gsize size);

Allocate a new import target suitable for this class. Implementing classes will define the actual content of the target.

#### Parameters

import | an EImport |
type | type, up to implementor |
size | Size of object to allocate. |

### e_import_target_free ()

    void
    e_import_target_free (EImport *import,
                          gpointer target);

Free a target. The implementing class can override this method to free custom targets.

#### Parameters

import | an EImport |
target | the target to free |

                                        const EImportHookTargetMap *map);

`class` : The dervied EimportHook class. `map` : A map used to describe a single EImportTarget type for this class.

Add a targe tmap to a concrete derived class of EImport. The target map enumates the target types available for the implenting class.
