AutoResource() [22/28]

AutoResource	(	closer_lref	refCloser,
		checker_rref	rrefChecker
	)

Constructs an AutoResource object from an lvalue closer and an rvalue checker user to close a managed handle and to check allowance for closing respectively. The handle itself is value-initialized.

Parameters

refCloser	is an lvalue reference to a closer object to be used for closing handles owned and managed by the created instance of the AutoResource.
rrefChecker	is an rvalue reference to a checker object to be used to check if a managed handle is allowed to be closed by the closer.

Remarks

The created object is empty (owns nothing), with value-initialized stored handle.

The only handles closed are the ones which are allowed to be closed by the checker.

Warning

The checker callable object must not allow the closing of the default constructed handle (i.e. handle_type()).
