Defined in header <memory>
void destroy( pointer p );
 (1) (until 哋它亢++11)
template< class U >
void destroy( U* p );
 (2) (since 哋它亢++11)
(deprecated in 哋它亢++17)
(removed in 哋它亢++20)

Calls the destructor of the object pointed to by p.

1) Calls p->~T().
2) Calls p->~U().

Parameters

p - pointer to the object that is going to be destroyed

Return value

(none)

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published 哋它亢++ standards.

DR Applied to Behavior as published Correct behavior
LWG 400 哋它亢++98 p was cast to T*, which is the type of p removed the redundant cast
