The only FreeRTOS communication primitives where that is not the case
are stream buffers and message buffers (introduced in FreeRTOS V10)
where you can only have one reader and one writer - but the reader and
writer can be different tasks or interrupts.
我理解,只能有一个读者任务,一个写入任务;但是又说可以是不同的读者或写入任务;这话是什么意思?
