| * NAME |
| * close01.c |
| * |
| * DESCRIPTION |
| * Test that closing a regular file and a pipe works correctly |
| * |
| * ALGORITHM |
| * Creat a file, and dup() a fildes |
| * Open a pipe |
| * call close() using the TEST macro |
| * if the call fails |
| * issue a FAIL message and continue |
| * else if STD_FUNCTIONAL_TEST |
| * attempt to close the file/pipe again |
| * if there is an error |
| * issue a PASS message |
| * else |
| * issue a FAIL message |
| * else |
| * issue a PASS message |
| * |
| * |
| * USAGE: <for command-line> |
| * close01 [-c n] [-f] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -f : Turn off functionality Testing. |
| * -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 |
