*******************************************************************************
* -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.
*
* - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -
*******************************************************************************
*
* main() creates all the demo application tasks, then starts the scheduler.
* The web documentation provides more details of the standard demo application
* tasks, which provide no particular functionality but do provide a good
* example of how to use the FreeRTOS API.
*
* In addition to the standard demo tasks, the following tasks and tests are
* defined and/or created within this file:
*
* "Check" task - This only executes every five seconds but has a high priority
* to ensure it gets processor time. Its main function is to check that all the
* standard demo tasks are still operational. While no errors have been
* discovered the check task will print out "OK" and the current simulated tick
* time. If an error is discovered in the execution of a task then the check
* task will print out an appropriate error message.
