## Description

This container class provides a data access for a specific data of extension subtag.

## Functions

### lt_ext_module_data_new ()

    lt_ext_module_data_t *
    lt_ext_module_data_new (size_t size,
                            lt_destroy_func_t finalizer);

Create a new instance of lt_ext_module_data_t. this function allows to create an inherited instance like:

    1
    2
    3
    4
    struct _my_module_data_t {
    lt_ext_module_data_t  parent;
    ...own members...
    };

#### Parameters

size | real size to allocate memory for the object. |
finalizer | a callback function to destroy the content. | [scope async]

#### Returns

a lt_ext_module_data_t.

[transfer full]

### lt_ext_module_data_ref ()

    lt_ext_module_data_t *
    lt_ext_module_data_ref (lt_ext_module_data_t *data);

Increases the reference count of `data` .

#### Parameters

data | a lt_ext_module_data_t. |

#### Returns

the same `data` object.

[transfer none]

### lt_ext_module_data_unref ()

    void
    lt_ext_module_data_unref (lt_ext_module_data_t *data);

Decreases the reference count of `data` . when its reference count drops to 0, the object is finalized (i.e. its memory is freed).

#### Parameters

data | a lt_ext_module_data_t. |

## Types and Values

### lt_ext_module_data_t

    typedef struct {
    	lt_pointer_t dummy[8];
    } lt_ext_module_data_t;

All the fields in the lt_ext_module_data_t structure are private to the lt_ext_module_data_t implementation.

#### Members

lt_pointer_t `dummy`[8]; | a dummy pointer for alignment. |
