void deallocate_bytes( void* p, std::size_t nbytes, std::size_t alignment = alignof(std::max_align_t) ); | (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(nbytes, alignment)
, typically through a call to allocate_bytes(nbytes, alignment)
.
Equivalent to resource()->deallocate(p, nbytes, alignment);
.
p | - | pointer to memory to deallocate |
nbytes | - | the number of bytes originally allocated |
alignment | - | the alignment originally allocated |
Throws nothing.
This function was introduced for use with the fully-specialized allocator std::pmr::polymorphic_allocator<>
, but it may be useful in any specialization.
(C++20) | frees raw memory obtained by allocate_object (public member function) |
(C++20) | destroys and deallocates an object (public member function) |
[static] | deallocates storage using the allocator (public static member function of std::allocator_traits<Alloc> ) |
deallocates memory (public member function of std::pmr::memory_resource ) |
