std::pmr::polymorphic_allocator<T>::deallocate_object

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(n).

# Declarations

template< class U >
void deallocate_object( U* p, std::size_t n = 1 );

(since C++20)

# Parameters

• p: pointer to memory to deallocate
• n: number of objects of type U the memory was for

# Notes

This function was introduced for use with the fully-specialized allocator std::pmr::polymorphic_allocator<>, but it may be useful in any specialization.
