From 65c8be380431eebe4d70d130bd38563f8df9a7d7 Mon Sep 17 00:00:00 2001 From: "A. Wilcox" Date: Wed, 13 Mar 2019 11:16:11 -0500 Subject: fcntl.h: define O_TTY_INIT to 0 POSIX: "[If] either O_TTY_INIT is set in oflag or O_TTY_INIT has the value zero, open() shall set any non-standard termios structure terminal parameters to a state that provides conforming behavior." The Linux kernel tty drivers always perform initialisation on their devices to set known good termios values during the open(2) call. This means that setting O_TTY_INIT to zero is conforming. --- include/fcntl.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/include/fcntl.h b/include/fcntl.h index f6c192f5..1fba777d 100644 --- a/include/fcntl.h +++ b/include/fcntl.h @@ -36,8 +36,9 @@ int openat(int, const char *, int, ...); int posix_fadvise(int, off_t, off_t, int); int posix_fallocate(int, off_t, off_t); -#define O_SEARCH O_PATH -#define O_EXEC O_PATH +#define O_SEARCH O_PATH +#define O_EXEC O_PATH +#define O_TTY_INIT 0 #define O_ACCMODE (03|O_SEARCH) #define O_RDONLY 00 -- cgit v1.2.1
