+<p>This simple example of the use of <codeph>__ASSERT_ALWAYS</codeph> shows
+how to panic on an illegal value. </p>
+<p>Suppose the member function <codeph>F()</codeph> in class <codeph>CMyClass</codeph>,
+takes a <codeph>TInt</codeph> argument which must always be zero or positive. </p>
+<codeblock id="GUID-21213FE1-90B2-5218-BD0C-E2D598962AD6" xml:space="preserve">void CMyClass::F(TInt aValue)
+ {
+ _LIT(KMyPanicDescriptor, "My panic text");
+
+ __ASSERT_ALWAYS(aValue &gt;= 0,User::Panic(KMyPanicDescriptor, aValue));
+ ...
+ /* main body of the function */
+ ...
+ }</codeblock>
+<p>If the caller passes a value which is negative, the current thread is panicked. </p>
+</conbody></concept>
