## SYNOPSIS

`#include <memory>`

### Public Member Functions

constexpr **default\_delete** () noexcept=**default**\
 Default constructor.  template\<**typename** \_Up , **typename**  = \_Require\<is\_convertible\<\_Up\*, \_Tp\*\>\>\> constexpr **default\_delete** (const **default\_delete**\< \_Up \> &) noexcept\
 Converting constructor.  constexpr **void** **operator()** (\_Tp \***\_\_ptr**) const\

## Constructor & Destructor Documentation

### template\<typename \_Tp \> constexpr std::default\_delete\< \_Tp \>::default\_delete ()` [constexpr]`, ` [default]`, ` [noexcept]`

Default constructor.

### template\<typename \_Tp \> template\<typename \_Up , typename = \_Require\<is\_convertible\<\_Up\*, \_Tp\*\>\>\> constexpr std::default\_delete\< \_Tp \>::default\_delete (const default\_delete\< \_Up \> &)` [inline]`, ` [constexpr]`, ` [noexcept]`

Converting constructor. Allows conversion from a deleter for objects of another type, `_Up`, only if `_Up*` is convertible to `_Tp*`.

## Member Function Documentation

### template\<typename \_Tp \> constexpr void std::default\_delete\< \_Tp \>::operator() (\_Tp \* \_\_ptr) const` [inline]`, ` [constexpr]`

Calls `delete __ptr`
