AutoResource() [16/28]

AutoResource	(	closer_rref	rrefCloser,
		checker_lref	refChecker
	)

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

Parameters

rrefCloser	is an rvalue reference to a closer object passed using move semantics and used for closing handles owned and managed by the created instance of the AutoResource.
refChecker	is an lvalue reference to a checker object to be used for checking if a handle managed by the instance of the AutoResource is allowed to be closed. The default class of checkers is a DefaultResourceHandleChecker.

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()).
