This value +is platform-dependent and does not change after NSPR is initialized. + + +Description +----------- + +The value returned by ``PR_TicksPerSecond()`` lies between +``PR_INTERVAL_MIN`` and ``PR_INTERVAL_MAX``. + +The relationship between a :ref:`PRIntervalTime` tick and standard clock +units is platform-dependent. PR\_\ ``PR_TicksPerSecond()`` allows you to +discover exactly what that relationship is. Seconds per tick (the +inverse of PR\_\ ``PR_TicksPerSecond()``) is always between 10 +microseconds and 1 millisecond. |
