MFC for Windows CE introduces a new socket class, called CCeSocket. Windows CE doesn't inherently support asynchronous socket communication, but the CCeSocket class provides asynchronous notification for certain types of socket events. If you require asynchronous event notification, you should always use the CCeSocket class when writing socket application for Windows CE.
See the following topics for information about the MFC for Windows CE socket classes.
To see where the Windows CE sockets classes fit into the Windows CE class hierarchy, see Classes Derived from CObject.
