Redefining the priority.
Priority value 0 has the highest priority, priority value 7 has the lowest priority.
A message with priority 6 can be superseded by a message with priority 4 (if
the messages are sent at the same time). The parameters InhibitTime and
EventTime
are not explicitly specified when calling up the function. In this
case, the default values are used.
