Semantics

The priority clause speciﬁes a hint for the task execution order of tasks generated by the construct on which it appears in the priority-value argument. Among all tasks ready to be executed, higher priority tasks (those with a higher numerical priority-value) are recommended to execute before lower priority ones. The default priority-value when no priority clause is speciﬁed is zero (the lowest priority). If a speciﬁed priority-value is higher than the max-task-priority-var ICV then the implementation will use the value of that ICV. A program that relies on the task execution order being determined by the priority-value may have unspeciﬁed behavior.
