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.|
The |

Parameters
| lhs, rhs | - | thread identifiers to compare |
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.Complexity
Constant.
