# BoolStruct Structure

Supports the WRL infrastructure and is not intended to be used directly from your code.

## Syntax

```cpp
struct BoolStruct;
```

## Remarks

The `BoolStruct` structure defines whether a `ComPtr` is managing the object lifetime of an interface. `BoolStruct` is used internally by the [BoolType()](comptr-class.md#operator-microsoft-wrl-details-booltype) operator.

## Members

### Public Data Members

[BoolStruct::Member](#member) | Specifies that a [ComPtr](comptr-class.md) is, or is not, managing the object lifetime of an interface.

## Inheritance Hierarchy
