flyweight_factory_new()

FlyweightFactory flyweight_factory_new	(	size_t	class_size,
		int	is_threadsafe,
		FlyweightMethodsIF	methods
	)

define class for flyweight

Parameters

[in]	class_size	size of instance which defined in user side.
[in]	is_threadsafe	if !=0, ensure threadsafe to create new class instace, please set !=0 if you want to use this API on multi thread
[in]	methods	for generating class instance If NULL, use defautlt. If not NULL, override methods. override NULL, this method is no effect. destructor is called at free

Return values

!=NULL	this class handle
NULL	error
