Module: Standard C++ Library Library: Language support
Function
Storage deallocation functions implicitly called by the corresponding delete expressions to deallocate storage previously allocated by one of the matching allocation functions
#include <new>
namespace std {
struct nothrow_t {};
extern const nothrow_t nothrow;
}
void operator delete(void*) throw();
void operator delete(void*, const std::nothrow_t&) throw();
void operator delete[](void*) throw();
void operator delete[](void*, const std::nothrow_t&) throw();
void operator delete(void*, void*) throw();
void operator delete[](void*, void*) throw();
The library provides definitions for six overloads of the global operator delete. The functions are implicitly called as the second step (after the call to the destructor, if any) during the evaluation of the corresponding delete expression to deallocate storage previously allocated by one of the matching allocation functions (::operator new). Replacements for the replaceable forms of the functions should always paired with the replacements for the corresponding overload of operator new.
void operator delete(void*) throw(); void operator delete(void*, const std::nothrow_t&) throw();
Deallocation functions implicitly called by a delete expression to deallocate storage previously allocated by the matching ::operator new (std::size_t) or ::operator new (std::size_t, std::nothrow&), respectively. A C++ program may replace these functions.
void operator delete[](void*) throw(); void operator delete[](void*, const std::nothrow_t&) throw();
Deallocation functions implicitly called by a delete expression to deallocate storage previously allocated by the matching ::operator new[] (std::size_t) or ::operator new[] (std::size_t, std::nothrow&), respectively. A C++ program may replace these functions.
void operator delete(void*, void*) throw(); void operator delete[](void*, void*) throw();
Default functions implicitly called when the initialization in a placement new expression that invokes the placement form of operator new terminates by throwing an exception. A C++ program may not replace these functions.
