                        lt_destroy_func_t finalizer);

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

...own members...
};

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

Increases the reference count of data .

data

the same data object.

[transfer none]

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).
