基于C语言实现环形缓冲区/循环队列 这里分享一个自己用纯C实现的环形缓冲区。 环形缓冲区有很多作用,比如嵌入式中的通信可以用环形缓冲区作为信道,一个线程往里放字节,一个线程取字节进行处理,只要保证取的速度大于读的速度,就可以保证通信顺畅进行,不丢一个字节。 简要介绍: 环形缓冲区其实就是一个队列,里头的元...
Functions: Function PrototypesIt is now considered good form to use function prototypes for all functions in your program. A prototype declares the function name, its parameters, and its return type to the rest of the program prior to the function's actual declaration. To understand why function...

Add function prototypes to the headers and start each source file with function prototypes for its local (static) functions. All calls to functions are covered, but this method requires typing the interface for each local function twice in the source file. Change all function declarations and defi...
