18 * Test Name: flistxattr02
19 *
20 * Description:
21 * 1) flistxattr(2) fails if the size of the list buffer is too small
22 * to hold the result.
23 * 2) flistxattr(2) fails if fd is an invalid file descriptor.
24 *
25 * Expected Result:
26 * 1) flistxattr(2) should return -1 and set errno to ERANGE.
27 * 2) flistxattr(2) should return -1 and set errno to EBADF.
