A‘head’ index - the point at which the producer inserts items into the buffer. 2)tail index 可以指向任何位置。 A‘tail’ index - the point at which the consumer finds the next item in the buffer. 3)队列满:当 head index 前进一个 单位后等于 tail index 的时候,队列就满了,这个时候其实...

Imagine, for example, that the buffer is full, and that Push() is trying unsuccessfully to insert a new element, because it reads that head=tail and C!=0. Then, the consumer thread pops a value, and stores the next value of tail with release semantics at the place tagged <=== T ...

Data from a UART is stored in a circular buffer which is filled in the EXAMPLE_ReadRingBuffer function where the index is also calculated. This function, however, is performed from when a character is received and this occurs in interrupt. In my case, I need to fill a circular buffer ...
