What happened and what to do
Published on February 5, 2026, the article describes eight ways to implement defer in C as alternatives to waiting for the feature to be added to the language standard. It also discusses the portability of these approaches and the trade-offs involved in cleanup patterns.
A company maintaining C software can evaluate the options with tests across its compilers and platforms, document a resource-cleanup standard, and incorporate it into code review. The choice should account for portability, readability, and the risk of inconsistent resource release.
