Declaration [src]
JSCValue*
jsc_value_new_functionv (
  JSCContext* context,
  const char* name,
  GCallback callback,
  gpointer user_data,
  GDestroyNotify destroy_notify,
  GType return_type,
  guint n_parameters,
  GType* parameter_types
)
Description [src]
Create a function in context. If name is NULL an anonymous function will be created.
When the function is called by JavaScript or jsc_value_function_call(), callback is called
receiving the function parameters and then user_data as last parameter. When the function is
cleared in context, destroy_notify is called with user_data as parameter.
Note that the value returned by callback must be fully transferred. In case of boxed types, you could use
G_TYPE_POINTER instead of the actual boxed GType to ensure that the instance owned by JSCClass is used.
If you really want to return a new copy of the boxed type, use #JSC_TYPE_VALUE and return a JSCValue created
with jsc_value_new_object() that receives the copy as instance parameter.
