From 5f10701fdc7a4708101f7931c15b7146c4f06690 Mon Sep 17 00:00:00 2001 From: Paul Pluzhnikov Date: Mon, 31 Dec 2018 19:14:28 -0800 Subject: libio: use stdout in puts and putchar, etc [BZ #24051]. GLIBC explicitly allows one to assign a new FILE pointer to stdout and other standard streams. printf and wprintf were honouring assignment to stdout and using the new value, but puts, putchar, and wide char variants did not. The stdout part is fixed here. The stdin part will be fixed in a followup. --- libio/putchar_u.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'libio/putchar_u.c') diff --git a/libio/putchar_u.c b/libio/putchar_u.c index 37d03ad364..1eebf0fc8f 100644 --- a/libio/putchar_u.c +++ b/libio/putchar_u.c @@ -23,6 +23,6 @@ int putchar_unlocked (int c) { - CHECK_FILE (_IO_stdout, EOF); - return _IO_putc_unlocked (c, _IO_stdout); + CHECK_FILE (stdout, EOF); + return _IO_putc_unlocked (c, stdout); } -- cgit 1.4.1
