void deallocate ( T * p, std:: size_t n ) ;
(since C++17)

Deallocates the storage pointed to by p , which must have been allocated from a std::pmr::memory_resource x that compares equal to * resource ( ) using x. allocate ( n * sizeof ( T ) , alignof ( T ) ) .

Equivalent to this - > resource ( ) - > deallocate ( p, n * sizeof ( T ) , alignof ( T ) ) ; .

Parameters

p - pointer to memory to deallocate
n - the number of objects originally allocated
