(7) | (since C++20) |
Compares two thread identifiers.
1-2) Checks whether lhs and rhs represent either the same thread, or no thread.
3-7) Compares lhs and rhs in an unspecified total ordering.

[edit] Parameters
lhs, rhs | - | thread identifiers to compare |
[edit] Return value
1-6) true if the corresponding relation holds, false otherwise.
7) std::strong_ordering::less if lhs is less than rhs in the total ordering; otherwise std::strong_ordering::greater if rhs is less than lhs in the total ordering; otherwise std::strong_ordering::equal.
[edit] Complexity
Constant.
