(rtmin_handler): Set it. (thr, do_child, do_test): Also check rtmin_code. 2004-04-14 Jakub Jelinek * rt/Makefile (tests): Add tst-mqueue7. (tst-mqueue7-ARGS): Set. * rt/tst-mqueue7.c: New test. 2004-04-13 Jakub Jelinek * rt/Makefile (tests): Add tst-mqueue5 and tst-mqueue6. * rt/tst-mqueue1.c (do_one_test): Bitwise or check_attrs () into result instead of replacing it. Use TEMP_FAILURE_RETRY around waitpid, kill child if waitpid failed. (do_test): Bitwise or check_attrs () into result instead of replacing it. Change temp mq name. * rt/tst-mqueue5.c: New test. * rt/tst-mqueue6.c: New test. * rt/tst-mqueue.h: Include stdio.h, unistd.h, sys/uio.h. (temp_mq_list, delete_temp_mqs): Remove. (temp_mq_fd): New variable. (do_cleanup, do_prepare): New functions. (add_temp_mq): Rewritten to use a temp file. (PREPARE): Define. (CLEANUP_HANDLER): Change to do_cleanup (). * rt/tst-timer3.c: Don't fail if _POSIX_THREADS is not available. 2004-04-13 Thorsten Kukuk * sysdeps/s390/ffs.c: Include limits.h 2004-04-13 Kaz Kojima * sysdeps/unix/sysv/linux/sh/sysdep.h (SUBSTITUTE_ARGS_1, SUBSTITUTE_ARGS_2, SUBSTITUTE_ARGS_3, SUBSTITUTE_ARGS_4, SUBSTITUTE_ARGS_5, SUBSTITUTE_ARGS_6, SUBSTITUTE_ARGS_7): Load argument values into temporary variables. --- rt/tst-mqueue6.c | 305 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 305 insertions(+) create mode 100644 rt/tst-mqueue6.c (limited to 'rt/tst-mqueue6.c') diff --git a/rt/tst-mqueue6.c b/rt/tst-mqueue6.c new file mode 100644 index 0000000000..f4fdb02c6c --- /dev/null +++ b/rt/tst-mqueue6.c @@ -0,0 +1,305 @@ +/* Test mq_notify. + Copyright (C) 2004 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Jakub Jelinek , 2004. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
