From 9efc8b95af3b3e832d7d3660119c3d487d40d16e Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 23 Aug 2001 08:36:47 +0000 Subject: * libio/tst-ungetwc1.c (main): Add a const to quiet a warning. * nss/test-netdb.c (test_hosts): Don't use MAXHOSTNAMELEN. Instead, use dynamic buffer to test gethostname's ENAMETOOLONG error. --- nss/test-netdb.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'nss/test-netdb.c') diff --git a/nss/test-netdb.c b/nss/test-netdb.c index f52724039d..8ae6d12fc0 100644 --- a/nss/test-netdb.c +++ b/nss/test-netdb.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1998, 1999, 2000 Free Software Foundation, Inc. +/* Copyright (C) 1998,99,2000,01 Free Software Foundation, Inc.
