C is commonly employed for process programming in utilizing operating methods and embedded process purposes,[forty] mainly because C code, when published for portability, may be used for some reasons, however when essential, program-certain code can be used to accessibility specific components addresses and to perform type punning to match externally imposed interface specifications, which has a very low run-time desire on program resources.
