Monotonic clocks and OS X

SDL Development
1

I’m working on some patches to implement monotonic clocks on OS X (die gettimeofday die)

While working on that I noticed one odd thing, the test rig isn’t calling SDL_Init only SDL_VideoInit. And by doing that it bypasses the call to SDL_StartTick() that is performed in SDL_InitSubsystem ?

Before I go nuts and refactor the initialization, I’d like input on a “clean and simple way” to ensure that SDL_StartTick is always run?

If you’re willing to take the hit of an if statement in GetTicks(), you can
keep a static bool initializer around…On Thu, May 2, 2013 at 2:50 PM, Edward Rudd wrote:

I chatted with ryan some yesterday and committed in a quick workaround. Where by basically moved some stuff around slightly just hit the initiailzer from SDL_InitSubsystems (as it was before) and hit it also from SDL_VideoInit…

But good news is we have proper monotonic time on OS X & Linux now…On May 4, 2013, at 6:09 , Sam Lantinga wrote:
