The ID is allocated when the thread or process is created.</p> <p>The main motivation for the ID is to provide assistance for debuggers; it provides an easy way to identify threads and processes.</p> <p>In general, applications and servers can use IDs for thread and process identification or, indeed, for whatever purpose that suits them.</p> <p>While a thread ID is a property of the thread, it can be retrieved from the thread by calling RThread::Id(). The ID is encapsulated by a TThreadId object that is returned by the function.</p> <p>The <codeph>TThreadId</codeph> class provides <codeph>==</codeph> and <codeph>!=</codeph> operators for comparing two thread IDs.</p> <p>The process ID is similar; it can be retrieved from the process by calling RProcess::Id(), and is encapsulated by a TProcessId object returned by the function.</p> </conbody></concept>
