Is there a way to know if std::chrono::monotonic_clock is defined?
- by Vicente Botet Escriba
C++0X N3092 states that monotonic_clock is optional.
20.10.5.2 Class monotonic_clock [time.clock.monotonic]
1 Objects of class monotonic_clock
represent clocks for which values of
time_point never decrease as physical
time advances. monotonic_clock may be
a synonym for system_clock if
system_clock::is_monotonic is true.
** 2 The class monotonic_clock is
conditionally supported.**
Is there a way using SFINAE or another technique to define a traits class that states if monotonic_clock is defined?
struct is_monotonic_clock_defined;
If yes, how? If not, shouldn't the standard define macro that gives this information at preprocessing time?
