| * NAME |
| * readv03.c |
| * |
| * DESCRIPTION |
| * Testcase to check the error condition of the readv(2) system call |
| * when fd refers to a directory. |
| * |
| * CALLS |
| * readv() |
| * |
| * ALGORITHM |
| * loop if that option was specified |
| * call readv() when fd refers to a directory. |
| * check the errno value |
| * issue a PASS message if we get EISDIR - errno 21 |
| * otherwise, the tests fails |
| * issue a FAIL message |
| * call cleanup |
| * |
| * USAGE$ |
| * readv03 |
| * |
| * HISTORY |
| * 05/2002 Ported by Jacky Malcles |
| * |
| * RESTRICTIONS |
| * None |
