+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
+Symbian OS) 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>

+<section><title>Description</title> <p>The 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>
