From 5b2644cafc8a619b617ba0fbb5473667dbd634ba Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Thu, 14 May 2015 13:43:01 -0500 Subject: Promote reset (actually write a new one using the simple man 4 console_codes terminal reset escape sequence) and add gettty() function to lib so terminal gets reset even when we redirect stdout/stderr. (This is apparently the expected behavior.) --- lib/interestingtimes.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'lib/interestingtimes.c') diff --git a/lib/interestingtimes.c b/lib/interestingtimes.c index cea5039f..85b8eb4c 100644 --- a/lib/interestingtimes.c +++ b/lib/interestingtimes.c @@ -5,6 +5,15 @@ #include "toys.h" +int xgettty(void) +{ + int i, j; + + for (i = 0; i<3; i++) if (isatty(j = (i+1)%3)) return j; + + return xopen("/dev/tty", O_RDWR); +} + // Quick and dirty query size of terminal, doesn't do ANSI probe fallback. // set x=80 y=25 before calling to provide defaults.
