18 * Test Name: removexattr02
19 *
20 * Description:
21 * 1) removexattr(2) fails if the named attribute does not exist.
22 * 2) removexattr(2) fails if path is an empty string.
23 * 3) removexattr(2) fails when attempted to read from a invalid address.
24 *
25 * Expected Result:
26 * 1) removexattr(2) should return -1 and set errno to ENODATA.
27 * 2) removcxattr(2) should return -1 and set errno to ENOENT.
28 * 3) removexattr(2) should return -1 and set errno to EFAULT.
