std::pmr::p...locate_bytes(3) C++ Standard Libary std::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 allocated from a std::pmr::memory_resource x that compares equal to *resource(), using 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 alloca- tor std::pmr::polymorphic_allocator<>, but it may be useful in any special- ization.
