The idea is neither to be an extensive testing nor to check for any specific Linux test. * sysvipc/Makefile (tests): Add test-sysvmsg. * sysvipc/test-sysvmsg.c: New file. * test-skeleton.c (FAIL_UNSUPPORTED): New define. --- ChangeLog | 4 ++ sysvipc/Makefile | 2 + sysvipc/test-sysvmsg.c | 128 +++++++++++++++++++++++++++++++++++++++++++++++++ test-skeleton.c | 2 + 4 files changed, 136 insertions(+) create mode 100644 sysvipc/test-sysvmsg.c diff --git a/sysvipc/Makefile b/sysvipc/Makefile index 5f3479e..73bb9cf 100644 --- a/sysvipc/Makefile +++ b/sysvipc/Makefile @@ -30,6 +30,8 @@ routines := ftok \ semop semget semctl semtimedop \ shmat shmdt shmget shmctl +tests := test-sysvmsg + include ../Rules CFLAGS-msgrcv.c = -fexceptions -fasynchronous-unwind-tables diff --git a/sysvipc/test-sysvmsg.c b/sysvipc/test-sysvmsg.c new file mode 100644 index 0000000..65a1a3a --- /dev/null +++ b/sysvipc/test-sysvmsg.c @@ -0,0 +1,128 @@ +/* Basic tests for SYSV message queue functions. + Copyright (C) 2016 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + 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.
