std::pmr::polymorphic_allocator::deallocate(3) C++ Standard Libary std::pmr::polymorphic_allocator::deallocate(3)


std::pmr::polymorphic_allocator::deallocate - std::pmr::polymorphic_allocator::deallocate


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));.


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


Throws nothing.
