[[nodiscard]] void* allocate(std::size_t bytes, std::size_t alignment = alignof(std::max_align_t)); | (since C++20) |
Allocates storage with a size of at least bytes
bytes. The returned storage is aligned to the specified alignment
if such alignment is supported, and to alignof(std::max_align_t)
otherwise.
Equivalent to return do_allocate(bytes, alignment);
.
Throws an exception if storage of the requested size and alignment cannot be obtained.
