- * Rules of use of the given emulation uCOS in Win32:
- *
- * 1. All Win32-threads which interact with uCOS-tasks should initialize
- * critical section by call OS_INIT_CRITICAL() (if defined USE_CRITICAL_SECTION
- * in os_cpu_c.c). They can be considered as handlers of interrupts.
- * 2. Function printf() and it similar should be made in critical section as
- * the console is shared resource and can cause deadlock of tasks ( see osprintf()
- * in the end of file ).
- * 3. It is necessary very closely use shared resources of Windows - they can cause
- * blocking of tasks.
- *
- * The given emulation starts each uCOS-task in separate thread. At any moment of time
- * only 0 or one from these threads can be active. (remaining in SUSPEND state, not considering
- * two service threads (have priorities 10 and 15). Each thread in SUSPEND state
- * must have SUSPEND counter = 1).
