******************************************************************************
|
|
* -NOTE- The Win32 port is a simulation (or is that emulation?) only! Do not
|
|
* expect to get real time behaviour from the Win32 port or this demo
|
|
* application. It is provided as a convenient development and demonstration
|
|
* test bed only. This was tested using Windows XP on a dual core laptop.
|
|
*
|
|
* In this example, one simulated millisecond will take approximately 40ms to
|
|
* execute. See the documentation page for the Windows simulator for an
|
|
* explanation of the slow timing:

|
|
* This is a simple FreeRTOS Windows simulator project that makes it easy to
|
|
* evaluate CyaSSL in a FreeRTOS environment on a standard desktop PC, and
|
|
* without any external hardware or interfaces being required.
|
|
*
|
|
* main() creates a TCP server task, which initialises CyaSSL, before creating a
|
|
* TCP client task. Both the server and client use TLS secured sockets.
|
|
*
|
|
* The client task repeatedly connects to the server, sends 10 messages, then
|
|
* disconnects. The server task prints the contents of each message to the
|
|
* console as they are received.
|
|
*
|
|
* CyaSSL objects are created and deleted as each socket connects and
|
|
* disconnects respectively.
|
|
*
|
|
* The server task is implemented in SecureTCPServerTask.c, and the client task
|
|
* in SecureTCPClientTask.c.
|
|
*

* Visit http://www.FreeRTOS.org/ssl for FreeRTOS + CyaSSL for demo
|
