AutoResource() [10/28]

AutoResource

(

checker_lref

refChecker

)

Constructs an AutoResource object from the specified lvalue reference to a checker object, with the value-initialized default handle and the default closer object.

Parameters

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 and closer.

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()).
