      These wrappers provide a portable object oriented interface for networking, multithreading,  
      GUI development, and file browsing.
      Programs written using them can be compiled under POSIX or MS Windows platforms without changing the code.

            This is a set of objects that provides an easy to use and object oriented 
            interface for dealing with TCP networking. There are currently two implementations,
            one for UNIX and another for all versions of Windows after Windows95.
            Both provide the exact same interface so programs written with them can be
            recompiled on either platform without a problem.
            <p>
              You also may want to take note of the <a href="other.html#timeout">timeout</a> object.
              It provides a mechanism which you can use to add a timeout to a network operation.

                  The implementation of this extension can be found 
                  <a href="dlib/threads/thread_pool_extension.h.html">here</a>.  It is 
                  implemented such that no memory allocations occur after the thread pool
                  has been constructed (the future object also doesn't perform any memory allocations or contain any system
                  resources such as mutex objects).

                This object represents a multithreaded object.  It is similar to 
                the <a href="#threaded_object">threaded_object</a> except it allows you to have many threads in a 
                single object rather than just one.

                  This extension adds a mechanism to automatically unlock a mutex.
                  Also note that this extension is included by dlib/threads.h so you don't have to include 
                  anything extra to get it.

            This component is a collection of various windowing widgets such as buttons,
            labels, text boxes, and so on.  It also includes the drawable
            interface, drawable_window, and font handling objects.  
            <a href="dlib/gui_widgets/widgets_abstract.h.html">dlib/gui_widgets/widgets_abstract.h</a> 
            defines all of the high level graphical widgets provided by this
            component that can appear in a drawable_window.  To view the specifications for the other members of this 
            component look at <a href="dlib/gui_widgets/fonts_abstract.h.html">dlib/gui_widgets/fonts_abstract.h</a>,

            <p>This component isn't actually a wrapper on top of OS APIs.  Rather, it is
            implemented on top of the <a href="#gui_core">gui_core</a> 
            component.  I put it on this page just because I expect that people would
            look here when searching for the sort of functionality provided by this component.
