56
 * -NOTE- The Win32 port is a simulation (or is that emulation?) only!  Do not
57
 * expect to get real time behaviour from the Win32 port or this demo
58
 * application.  It is provided as a convenient development and demonstration
59
 * test bed only.  This was tested using Windows XP on a dual core laptop.
60

61
 * - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -
62
 *******************************************************************************
63
 *
64
 * main() creates all the demo application tasks, then starts the scheduler.
65
 * The web documentation provides more details of the standard demo application
66
 * tasks, which provide no particular functionality but do provide a good
67
 * example of how to use the FreeRTOS API.
68
 *
69
 * In addition to the standard demo tasks, the following tasks and tests are
70
 * defined and/or created within this file:
71
 *
72
 * "Check" task - This only executes every five seconds but has a high priority
73
 * to ensure it gets processor time.  Its main function is to check that all the
74
 * standard demo tasks are still operational.  While no errors have been
75
 * discovered the check task will print out "OK" and the current simulated tick
76
 * time.  If an error is discovered in the execution of a task then the check
77
 * task will print out an appropriate error message.
