AutoResource() [18/28]

AutoResource	(	handle_rref	rrefHandle,
		closer_rref	rrefCloser,
		checker_lref	refChecker
	)

Constructs an AutoResource object from rvalues of a handle and a closer using move semantics and from an lvalue checker. The handle will be managed by the created object using the closer and the checker to close the handle and to get permission for it respectively.

Parameters

rrefHandle	is an rvalue reference to a resource handle which is to be owned and managed by the created object.
rrefCloser	is an rvalue reference to a closer object to be 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 object takes ownership of the handle, initializing its stored handle, closer and checker with the specified values.

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()).
