When you use the function call trace feature in stack mode, be careful of your timing when you toggle the feature between enabled/disabled. For example, if you call a function called <CODE>test()</CODE> when the feature is disabled, and then enable it from within the <CODE>test()</CODE> function, it will be inconsistent because the function will attempt to discard information from the stack at <CODE>__PROFILE_EXIT</CODE>, even though nothing was done at the function entry (<CODE>__PROFILE_ENTRY</CODE>). Log mode only obtains records at <CODE>__PROFILE_ENTRY</CODE>, and therefore you can change status at any point.</P> 25<P>Enable/disable switches are set separately for each trace buffer. Therefore one will not disable all.</P> 26<P>If this function is compiled for debugging, it will function properly. However, if compiled for the final ROM version (<CODE>FINALROM</CODE>) library, it will not do anything.</P> 27<H2>See Also</H2> 28<P><CODE><A href="OS_InitCallTrace.html">OS_InitCallTrace</A>, <A href="OS_EnableCallTrace.html">OS_EnableCallTrace</A>, <A href="OS_RestoreCallTrace.html">OS_RestoreCallTrace</A><BR></CODE></P> 29<H2>Revision History</H2> 30<P>2004/04/23 Initial version.</P> 31<hr><p>CONFIDENTIAL</p></body> 32</HTML>
