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 |
(since C++20) |
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.
