Subject: fcntl.h: define O_TTY_INIT to 0
X-Git-Tag: v1.1.23~67
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=65c8be380431eebe4d70d130bd38563f8df9a7d7;p=oweals%2Fmusl.git

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.
