Hi, man/man3/getcontext.3, which describes getcontext and setcontext, says "POSIX.1-2008 removes the specification of getcontext", making it look like setcontext was still present in POSIX.1-2008. It isn't. setcontext is removed as well. See https://pubs.opengroup.org/onlinepubs/9699919799.2008edition/xrat/V4_xsh_chap01.html in the table "Removed Functions and Symbols in Issue 7". It's just the rationale section https://pubs.opengroup.org/onlinepubs/9699919799.2008edition/xrat/V4_xsh_chap03.html where getcontext is mentioned but setcontext was forgotten. Bruno
