Consider the code block below

void foo()
{
    key = HwiP_disable();
    Sem_Post(handle);
    HwiP_restore(key);
}
If this is executed from a task context, the Sem_post() will invoke the scheduler. If a higher priority task is ready to run, it will pre-empt the calling task. When the Sem_post() returns, hardware interrupts will be re-enabled.
