| * NAME |
| * readdir02.c |
| * |
| * DESCRIPTION |
| * readdir02: try to readdir with Invalid directory stream descriptor dir. |
| * |
| * CALLS |
| * readdir(3) |
| * |
| * ALGORITHM |
| * loop if that option was specified |
| * call readdir() with an invalid file descriptor |
| * check the errno value |
| * issue a PASS message if we get EBADF - errno 9 |
| * otherwise, the tests fails |
| * issue a FAIL message |
| * call cleanup |
| * |
| * USAGE: <for command-line> |
| * readdir02 [-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. |
| * |
| * NOTE |
| * The POSIX standard says: |
| * The readdir() function may fail if: |
| * [EBADF] The dirp argument does not refer to an open directory stream. |
| * (Note that readdir() is not _required_ to fail in this case.) |
| * |
| * HISTORY |
| * 04/2002 - Written by Jacky Malcles |
| * |
| * 06/2003 - Added code to catch SIGSEGV and return TCONF. |
| * Robbie Williamson<robbiew@us.ibm.com> |
| * |
| * RESTRICTIONS |
| * none |
