#include <stdint.h>?

[fdoray, 2016/09/19 17:03:28]

Could it be base::TimeTicks instead of int64_t? Or that doesn't work with
DLLEXPORT __cdecl?

[grt (UTC plus 2), 2016/09/19 19:52:46]

Done.

[grt (UTC plus 2), 2016/09/19 19:52:46]

It's safest to stick to primitive types when crossing a boundary like this.
Since we expect the two binaries to be built with the same compiler at the same
time, it may be safe to use base::TimeTicks, but I'm inclined to be
conservative. Feel free to ask Siggi what he thinks if you find the int64_t bit
distasteful.
