public Value.functionv (Context context, string? name, Callback callback, void* user_data, DestroyNotify? destroy_notify, Type return_type, Type[]? parameter_types)
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 Type
to ensure that the instance owned by Class is used. If you really want to return a new
copy of the boxed type, use JSC_TYPE_VALUE and return a Value created with
Value.object that receives the copy as instance parameter.
