+Example - Using P.I.P.S OECORE </title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>This example application shows, using a P.I.P.S. (P.I.P.S. Is POSIX on
+the Symbian platform) program, the use of the LibpThread library to demonstrate
+simple multi-threading and synchronisation. </p>
+<p>The purpose is to create a basic multithreading example showing the usage
+of the LibpThread APIs. This example also shows how multi-threading is used
+to achieve concurrency in tasks and sharing of resources. </p>

+following sections provide more information about the steps that the example
+performs. </p> <p><b> Thread Synchronisation</b> </p> <p>The example creates
+three threads named ThreadOne, ThreadTwo and ThreadThree. The threads write
+"One", "Two" and "Three" five times in a text file. The text file, located
+in <filepath>epoc32\winscw\c\newfile.txt</filepath>, is used as a shared resource
+for all three threads. A mutex is used to ensure that first ThreadOne writes
+in the file, then ThreadTwo and then ThreadThree. If the mutex is not used
+all the threads can simultaneously write in the file. This can be seen by
+commenting out <codeph>pthread_mutex_lock</codeph> and <codeph>pthread_mutex_unlock</codeph> in
+the code. </p> </section>
