1.0.2 Changed the name of the template from RingBuffer to RingBuf in order to avoid a name conflict with and internal RingBuffer class used in the ARM version of the Arduino core. 1.0.1 Fix a mistake in pop documentation 1.0 Initial release. ...
ring在创建时调用的rte_ring_create函数中,大小必须是2的N次幂大小。 ring的push或者是pop,不是对整个对象进行操作,而是对对象的内存进行操作,换句话说push和pop塞入/得到的其实只能是对象的内存地址而已,所以性能很高。(这点也符合数据面的设计原则,严禁内存拷贝,如果是拷贝整个对象那么势必会产生额外的内存拷贝,传...
RingBuffer - an array with a Front and Back pointer and with implicit wraparound to the beginning of the array when reaching the end of the array when iterating from Front to Back Useful for providing O(1) push/pop at the end of the array (for Queue or Stack) while still having ...
