| * NAME |
| * ioctl01.c |
| * |
| * DESCRIPTION |
| * Testcase to check the errnos set by the ioctl(2) system call. |
| * |
| * ALGORITHM |
| * 1. EBADF: Pass an invalid fd to ioctl(fd, ..) and expect EBADF. |
| * 2. EFAULT: Pass an invalid address of arg in ioctl(fd, .., arg) |
| * 3. EINVAL: Pass invalid cmd in ioctl(fd, cmd, arg) |
| * 4. ENOTTY: Pass an non-streams fd in ioctl(fd, cmd, arg) |
| * 5. EFAULT: Pass a NULL address for termio |
| * |
| * USAGE: <for command-line> |
| * ioctl01 -D /dev/tty[0-9] [-c n] [-e] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
| * |
| * HISTORY |
| * 07/2001 Ported by Wayne Boyer |
| * 04/2002 Fixes by wjhuie |
| * |
| * RESTRICTIONS |
| * test must be run with the -D option |
| * test may have to be run as root depending on the tty permissions |
