<documentation>Starts execution of an active object and registers the object with the framework. This function is strongly OS-dependent and must be defined in the QP port to a particular platform.
The function takes six arguments:
'prio' is the priority of the active object. QP allows you to start up to 63 active objects, each one having a *unique* priority number between 1 and 63 inclusive, where higher numerical values correspond to higher priority (urgency) of the active object relative to the others.
'qSto[]' and 'qLen' arguments are the storage and size of the event queue used by this active object.
'stkSto' and 'stkSize' are the stack storage and size in bytes. Please note that a per-active object stack is used only when the underlying OS requies it. If the stack is not required, or the underlying OS allocates the stack internally, the stkSto should be NULL and/or stkSize should be 0.
'ie' is an optional initialization event that can be used to pass additional startup data to the active object. (Pass NULL if your active object does not expect the initialization event).</documentation>
