C patterns for systems code, libraries, and native extensions: module layout, function decomposition, status-enum errors, memory safety, and undefined behavior. Use when writing, reviewing, refactoring, or debugging C, working with malloc lifetimes, buffer overflows, sanitizers, or Valgrind, or building native extensions. For C++, see ia-cpp-systems.
