cloexec: add dup_cloexec This is needed to enforce correct semantics of mkostemp_safer. Meanwhile, it is one step closer to providing O_CLOEXEC support to open, as well as implementing portions of fcntl for mingw. * lib/cloexec.h (dup_cloexec): New prototype. Add copyright header and comments. * lib/cloexec.c (set_cloexec_flag): Add comments. (dup_cloexec): New function, with mingw implementation borrowed from... * lib/w32spawn.h (dup_noinherit): ...here. * modules/execute (Depends-on): Add cloexec. * modules/pipe (Depends-on): Likewise. * modules/cloexec (Depends-on): Add dup2. * modules/cloexec-tests (Files): New file. * tests/test-cloexec.c: Likewise.
