When thistimer is enabled, events are tagged with a timestamp as they are logged.<p>Seven routines are required: a timestamp routine, a timestamp routine thatguarantees interrupt lockout, a routine that enables the timer driver, aroutine that disables the timer driver, a routine that specifies theroutine to run when the timer hits a rollover, a routine that returns theperiod of the timer, and a routine that returns the frequency of thetimer.<p></blockquote><h4>INCLUDE FILES</h4><blockquote><p><p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./wvLib.html#top">wvLib</a></b>,<i>WindView User's Guide </i><hr><a name="wvTmrRegister"></a><p align=right><a href="rtnIndex.htm"><i>OS Libraries : Routines</i></a></p></blockquote><h1>wvTmrRegister( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong>wvTmrRegister( )</strong> - register a timestamp timer (WindView)</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>void wvTmrRegister ( UINTFUNCPTR wvTmrRtn, /* timestamp routine */ UINTFUNCPTR wvTmrLockRtn, /* locked timestamp routine */ FUNCPTR wvTmrEnable, /* enable timer routine */ FUNCPTR wvTmrDisable, /* disable timer routine */ FUNCPTR wvTmrConnect, /* connect to timer routine */ UINTFUNCPTR wvTmrPeriod, /* period of timer routine */ UINTFUNCPTR wvTmrFreq /* frequency of timer routine */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine registers a timestamp routine for each of the following: <dl><dt><i>wvTmrRtn</i><dd>a timestamp routine, which returns a timestamp when called (must be calledwith interrupts locked).<dt><i>wvTmrLockRtn</i><dd>a timestamp routine, which returns a timestamp when called (locks interrupts).<dt><i>wvTmrEnable</i><dd>an enable-timer routine, which enables the timestamp timer.<dt><i>wvTmrDisable</i><dd>a disable-timer routine, which disables the timestamp timer.<dt><i>wvTmrConnect</i><dd>a connect-to-timer routine, which connects a handler to be run when the timerrolls over; this routine should return NULL if the system clock tick is to beused.<dt><i>wvTmrPeriod</i><dd>a period-of-timer routine, which returns the period of the timer.<dt><i>wvTmrFreq</i><dd>a frequency-of-timer routine, which returns the frequency of the timer.</dl><p>If any of these routines is set to NULL, the behavior of instrumented code is undefined.<p></blockquote><h4>RETURNS</h4><blockquote><p>N/A</blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./wvTmrLib.html#top">wvTmrLib</a></b></body></html>⌨️ 快捷键说明
