BonoboMonikerSimple makes writing monikers really extremely easy. To implement a moniker you only have to write 1 function. To register create the moniker object you have to use only 1 call. It can't get much simpler. If you want to use monikers instead of implementing them, you probably want to see bonobo-moniker-util instead.
Few people need to implement monikers, but if they do, this is how they should do it:
Example 1. A cut down file: moniker implementation
Bonobo_Unknown
bonobo_moniker_file_resolve (BonoboMoniker               *moniker,
			     const Bonobo_ResolveOptions *options,
			     const CORBA_char            *requested_interface,
			     CORBA_Environment           *ev)
{
	const char    *fname = bonobo_moniker_get_name (moniker);
	Bonobo_Unknown retval;
	g_warning ("Fname 's'", fname);
	if (!strcmp (requested_interface, "IDL:Bonobo/Stream:1.0")) {
		BonoboStream *stream;
		stream = bonobo_stream_open ("fs", fname,
					     Bonobo_Storage_READ, 0664);
		if (!stream) {
			g_warning ("Failed to open stream 's'", fname);
			CORBA_exception_set (ev, CORBA_USER_EXCEPTION,
					     ex_Bonobo_Moniker_InterfaceNotFound, NULL);
			return CORBA_OBJECT_NIL;
		}
		return CORBA_Object_duplicate (BONOBO_OBJREF (stream), ev);
	}
	
	return CORBA_OBJECT_NIL;
}
    
After implementing the resolve function, you need to create the new moniker in your standard factory:
Example 2. Creating a new simple moniker
static BonoboObject *
bonobo_std_moniker_factory (BonoboGenericFactory *this,
			    const char           *object_id,
			    void                 *data)
{
	g_return_val_if_fail (object_id != NULL, NULL);
	if (!strcmp (object_id, "OAFIID:Bonobo_Moniker_File"))
		return BONOBO_OBJECT (bonobo_moniker_simple_new (
			"file:", bonobo_moniker_file_resolve));
	else
		return NULL;
}
    
typedef struct _BonoboMonikerSimple BonoboMonikerSimple;
A simplified BonoboMoniker.
typedef struct {
	BonoboMonikerClass parent_class;
} BonoboMonikerSimpleClass;
BonoboMonikerSimple's class.
Bonobo_Unknown (*BonoboMonikerSimpleResolveFn)
                                            (BonoboMoniker *moniker,
                                             const Bonobo_ResolveOptions *options,
                                             const CORBA_char *requested_interface,
                                             CORBA_Environment *ev);
Type of callback function that implements a simple moniker resolution.
| moniker: | the moniker | 
| options: | resolve options | 
| requested_interface: | the requested interface (repoid string) | 
| ev: | CORBA environment, in case an exception needs to be raised | 
| Returns : | a Bonobo_Unknown as the result of the resolution | 
BonoboMoniker* bonobo_moniker_simple_construct (BonoboMonikerSimple *moniker, const char *name, GClosure *resolve_closure);
Constructs a simple moniker
| moniker: | the moniker to construct | 
| name: | the name of the moniker eg. 'file:' | 
| resolve_closure: | the closure used to resolve the moniker | 
| Returns : | the constructed moniker or NULL on failure. | 
BonoboMoniker* bonobo_moniker_simple_new (const char *name, BonoboMonikerSimpleResolveFn resolve_fn);
Create a new instance of a simplified moniker.
| name: | the display name for the moniker | 
| resolve_fn: | a resolve function for the moniker | 
| Returns : | the moniker object | 
BonoboMoniker* bonobo_moniker_simple_new_closure (const char *name, GClosure *resolve_closure);
Create a new instance of a simplified moniker.
Instead of the Bonobo_ResolveOptions struct, the closure takes its contents as two arguments: BONOBO_TYPE_RESOLVE_FLAG and G_TYPE_LONG.
| name: | the display name for the moniker | 
| resolve_closure: | a closure for the resolve process. | 
| Returns : | the moniker object |
