It's not possible to delete a <a class="el" href="classGlib_1_1Thread.html" title="Represents a running thread.">Thread</a> object. If the thread is <em>not</em> joinable, its resources will be freed automatically when it exits.

<dl class="note"><dt><b>Note:</b></dt><dd>g_thread_exit() is not wrapped, because that function exits a thread without any cleanup. That's especially dangerous in C++ code, since the destructors of automatic objects won't be invoked.

<dd>
You might have noticed that the thread entry slot doesn't have the usual void* return value. If you want to return any data from your thread you can pass an additional output argument to the thread's entry slot. </dd></dl>

<p>Creates a new thread with the priority <em>priority</em>. </p>
<p>The stack gets the size <em>stack_size</em> or the default value for the current platform, if <em>stack_size</em> is <code>0</code>.</p>

Otherwise the thread will just disappear, when ready. If <em>bound</em> is <code>true</code>, this thread will be scheduled in the system scope, otherwise the implementation is free to do scheduling in the process scope. The first variant is more expensive resource-wise, but generally faster. On some systems (e.g. Linux) all threads are bound.</p>
<p>The new thread executes the function or method <em>slot</em> points to.
