std::pmr::polymorphic_allocator<T>::deallocate_object
|
(since C++20) |
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(U), alignof(U)), typically through a call to allocate_object<U>(n).
Equivalent to deallocate_bytes(p, n * sizeof(U), alignof(U));.
Parameters
| p | - | pointer to memory to deallocate |
| n | - | number of objects of type U the memory was for |
Exceptions
Throws nothing.
Notes
This function was introduced for use with the fully-specialized allocator std::pmr::polymorphic_allocator<>, but it may be useful in any specialization.
