From 12da14a59135fe331f294b91488c1bdf55b35b4e Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 26 Nov 2014 12:54:39 +0000 Subject: Fix warnings in fwscanf / rewind tests. This patch fixes "set but not used" warnings in the tests libio/bug-rewind.c and libio/bug-rewind2.c by checking the return values from fwscanf and making the tests fail if those values aren't as expected. Tested for x86_64. * libio/bug-rewind.c (do_test): Check fwscanf return values. * libio/bug-rewind2.c (do_test): Likewise. --- libio/bug-rewind.c | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'libio/bug-rewind.c') diff --git a/libio/bug-rewind.c b/libio/bug-rewind.c index 4f8242df3d..1734de285f 100644 --- a/libio/bug-rewind.c +++ b/libio/bug-rewind.c @@ -52,9 +52,19 @@ do_test (void) rewind (fptr); ret1 = fwscanf (fptr, L"%c%c", &arg1, &arg2); + if (ret1 != 2) + { + printf ("first fwscanf returned %d, expected 2\n", ret1); + return 3; + } rewind (fptr); ret2 = fwscanf (fptr, L"%c%n%c", &arg1, &num, &arg2); + if (ret2 != 2) + { + printf ("second fwscanf returned %d, expected 2\n", ret2); + return 4; + } if (arg2 != 'd') { -- cgit 1.4.1
