One way of thinking about these guidelines is as a specification for tools that happens to be readable by humans.
In other words, what would you like your code to look like in 5 years’ time, given that you can start now? The guidelines are focused on relatively high-level issues, such as interfaces, resource management, memory management, and concurrency.
Such rules affect application architecture and library design.
The aim of this document is to help people to use modern C effectively.
By “modern C ” we mean C 11 and C 14 (and soon C 17).
You will find some of the rules obvious or even trivial.
Please remember that one purpose of a guideline is to help someone who is less experienced or coming from a different background or language to get up to speed.Instead, they strongly recommend the use of a few simple “extensions” (library components) that make the use of the most error-prone features of C redundant, so that they can be banned (in our set of rules).The rules emphasize static type safety and resource safety.Consider these rules ideals for new code, opportunities to exploit when working on older code, and try to approximate these ideals as closely as feasible.Remember: Take the time to understand the implications of a guideline rule on your program.This is a set of core guidelines for modern C , C 14, taking likely future enhancements and ISO Technical Specifications (TSs) into account. The purpose of this document is to help developers to adopt modern C (C 11, C 14, and soon C 17) and to achieve a more uniform style across code bases.
