#feature-test-macros
The code review that started this series ended with a portability question: use std::osyncstream where it exists, fall back to a mutex where it does not. The feature-test macro __cpp_lib_syncbuf and <version> are the tool for exactly that. One file, the best available tool on each compiler. Episode 6 of the concurrent I/O series.
