std::pmr::p...locate_bytes(3) C++ Standard Libarystd::pmr::p...locate_bytes(3)

NAME
       std::pmr::polymorphic_allocator::deallocate_bytes  - std::pmr::polymor-
       phic_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 allo-
       cated from a
	  std::pmr::memory_resource x that compares equal to *resource(),  us-
       ing
	  x.allocate(nbytes,  alignment),  typically  through  a call to allo-
       cate_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  al-
       locator
	  std::pmr::polymorphic_allocator<>,  but it may be useful in any spe-
       cialization.
