os_handle

using v1::os_handle = void *

Minimum offset between two objects to avoid false sharing.

Guaranteed to be at least alignof(std::max_align_t) Part of c++17 but never implemented by clang or gcc. Maximum size of contiguous memory to promote true sharing. Guaranteed to be at least alignof(std::max_align_t) Part of c++17 but never implemented by clang or gcc.
