C0x

C0x is a designation that can refer to various contexts, depending on the field of use. In the realm of computer science and programming, C0x typically denotes the family of programming language standards associated with the C programming language, specifically the IEEE 1003.1 standards, known as POSIX.1. These standards outline specifications for maintaining compatibility between operating systems and C language implementations, facilitating portability and standardized development practices.

In the context of technology and networking, C0x can also refer to a range of protocols or code identifiers, often used in documentation or technical specifications to denote particular communication protocols or control codes. For instance, in networking, "C0x" might categorize certain command sets or status codes utilized within hardware or software communication systems.

Additionally, C0x could be used as a stylized or abbreviated term in various niche communities, projects, or product names, and its exact meaning can vary accordingly.

Without specific context, C0x remains a broad term with multiple interpretations. It is most commonly associated with the C programming language standards, where it signifies the evolution of the language's specifications, including notable versions such as C89, C99, C11, and C17. These standards serve as foundational references for compiler developers and programmers aiming for code portability and consistency across different computing platforms.
