- * 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
