GS_DEFINE_MODULE_TYPE()

#define             GS_DEFINE_MODULE_TYPE(TN, t_n, T_P)

Convenient macro used to declare a dynamicly registered type.

For example:

GS_DEFINE_MODULE_TYPE (FooBar, foo_bar, G_TYPE_OBJECT)

expands to:

static void     foo_bar_init       (FooBar      *self);	
static void     foo_bar_class_init (FooBarClass *klass);	

static GType foo_bar_type = 0;	
GType	
foo_bar_get_type () 
{ return foo_bar_type; } 

void 
foo_bar_register_type (GTypeModule *module)	
{	
  if (!foo_bar_type)
    {	
      static const GTypeInfo type_info =	
      {	
        sizeof (FooBarClass),						
        (GBaseInitFunc) NULL,					
        (GBaseFinalizeFunc) NULL,				
        (GClassInitFunc) foo_bar_class_init, 		
        NULL,
        NULL,
        sizeof (FooBar),							
        0,
        (GInstanceInitFunc) foo_bar_init			
      }; 

      foo_bar_type =	
        g_type_module_register_type (module, G_TYPE_OBJECT,	
                                     g_intern_static_string ("FooBar"), &type_info, 0);	
    } 
}

GnomeScanModule

typedef struct {
	void (* init)		(GnomeScanModule *module);
	void (* finalize)	(GnomeScanModule *module);
} GnomeScanModule;

A GnomeScanModule handle the loading, initialization, finalization and unloading of a module. If you want to extends Gnome Scan, you must implement two function, one for init and one for finalize, called gnome_scan_module_init() and gnome_scan_module_finalize(). You should prefix function prototypes with G_MODULE_EXPORT.

gnome_scan_module_new ()

GnomeScanModule*    gnome_scan_module_new               (gchar *filename);

Open and initialize a new module. This function should be used only by GnomeScanModuleManager.

The "filename" property

  "filename"                 gchar*                : Read / Write / Construct Only

The path to the shared object.

Default value: NULL
