The one exception to this is a task that is awaiting an external interrupt or an interval interrupt. Note that a task may explicitly unlock itself by calling UnlockTask(). A task will also become unlocked if it calls any of the sleep or delay routines. Note that multiple calls to LockTask() have the same effect as a single call to LockTask() assuming that no other calls are made that implicitly unlock the task. Compatibility The BasicX documentation indicates that a locked task will yield to a task that is awaiting an interrupt when the interrupt occurs. However, testing indicates that this is, in fact, not the case. This implementation allows an interrupt task to have priority over a locked task.
