* -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 | |
* documentation. | |
