PR_TicksPerSecond
|
|
=================
|
|
|
|
Returns the number of ticks per second currently used to determine the
|
|
value of :ref:`PRIntervalTime`.
|
|
|
|
|
|
Syntax
|
|
------
|
|
|
|
.. code::
|
|
|
|
#include <prinrval.h>
|
|
|
|
PRUint32 PR_TicksPerSecond(void);
|
|
|
|
|
|
Returns
|
|
~~~~~~~
|
|
|
|
An integer between 1000 and 100000 indicating the number of ticks per
|
|
second counted by :ref:`PRIntervalTime` on the current platform. 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.
