Non-member functions
(until C++20)
virtual void* do_allocate( std::size_t bytes, std::size_t alignment ) = 0;
(since C++17)
Allocates storage with a size of at least bytes bytes, aligned to the specified alignment.
alignment shall be a power of two.
[edit] Exceptions
Throws an exception if storage of the requested size and alignment cannot be obtained.
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 2843 | C++17 | handling of unsupported alignment contradictory | throws an exception |
