std::pmr::polymorphic_allocator::deallocate_bytes(3)

NAME
std::pmr::polymorphic_allocator::deallocate_bytes - std::pmr::polymorphic_allocator::deallocate_bytes

Synopsis
   void deallocate_bytes( void* p,
                        std::size_t nbytes, (since C++20)
                        std::size_t alignment =
   alignof(std::max_align_t) );
   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);.

Parameters
   p - pointer to memory to deallocate
   nbytes - the number of bytes originally allocated
   alignment - the alignment originally allocated

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.
