newSimple

fun newSimple(sizeofClosure: <Error class: unknown class>, data: <Error class: unknown class>? = null): Closure

Allocates a struct of the given size and initializes the initial part as a #GClosure.

This function is mainly useful when implementing new types of closures:

|[ typedef struct _MyClosure MyClosure; struct _MyClosure { GClosure closure; // extra data goes here };

static void my_closure_finalize (gpointer notify_data, GClosure *closure) { MyClosure *my_closure = (MyClosure *)closure;

// free extra data here }

MyClosure *my_closure_new (gpointer data) { GClosure *closure; MyClosure *my_closure;

closure = g_closure_new_simple (sizeof (MyClosure), data); my_closure = (MyClosure *) closure;

// initialize extra data here

g_closure_add_finalize_notifier (closure, notify_data, my_closure_finalize); return my_closure; } ]|

a floating reference to a new #GClosure

sizeofClosure

the size of the structure to allocate, must be at least sizeof (GClosure)

data

data to store in the @data field of the newly allocated #GClosure
