C语言是嵌入式软件的主要语言，由于嵌入式软件的专用性较强，实时性、安全性要求较高特点，其C语言编码规范与通用软件的C语言编码规范有较大的区别，目前国内尚缺少可以指导嵌入式软件C语言编码规范的标准，鉴于现状，制定《嵌入式软件 C语言编码规范》是非常必要的。-C language is the main language of embedded software, embedded software dedicated as strong, real-time, requiring high security features, its C language coding standard C language with generic software coding standard has a larger difference between the current China still lacks can guide embedded software coding standard C language standard, given the current situation, development of " embedded software coding standard C language"　is very necessary.
