This article explains what zero‑length arrays are, how they are defined in C, why they appear frequently in the Linux kernel as flexible array members, and provides a complete kernel‑style implementation showing creation, expansion, and cleanup of a dynamically sized integer array.
This article explains key GNU C extensions used in the Linux kernel—including typeof, zero‑length (flexible) arrays, case ranges, labeled initializers, variadic macros, function and variable attributes, built‑in functions, asmlinkage, and UL suffixes—showing why they exist, how to use them safely, and providing concrete code examples.
This article explains key GNU C extensions used throughout the Linux kernel—including typeof, zero‑length (flexible) arrays, case range labels, designated initializers, variadic macros, function and variable attributes, built‑in functions, asmlinkage and UL suffixes—showing why they exist and how to apply them safely with concrete code examples.
