bool operator<( thread::id lhs, thread::id rhs ) noexcept;	(3)	(since C++11)

bool operator>=( thread::id lhs, thread::id rhs ) noexcept;	(6)	(since C++11)

Compares two thread identifiers.

1-2) Checks whether lhs and rhs represent either the same thread, or no thread.

3-6) Compares lhs and rhs in such a way, that lhs and rhs are totally ordered.

Parameters

lhs, rhs

-

thread identifiers to compare

Return value

true if the corresponding relation holds, false otherwise.

Complexity

Constant.
