Function

CMSyncMightDrift

Returns a Boolean indicating whether it is possible for one timebase/clock to drift relative to the other.

Declaration

Boolean CMSyncMightDrift(CMClockOrTimebaseRef clockOrTimebase1, CMClockOrTimebaseRef clockOrTimebase2);

Discussion

A timebase can drift relative to another if they are ultimately mastered by clocks that can drift relative to each other.
