8 * Test Name: flistxattr02
9 *
10 * Description:
11 * 1) flistxattr(2) fails if the size of the list buffer is too small
12 * to hold the result.
13 * 2) flistxattr(2) fails if fd is an invalid file descriptor.
14 *
15 * Expected Result:
16 * 1) flistxattr(2) should return -1 and set errno to ERANGE.
17 * 2) flistxattr(2) should return -1 and set errno to EBADF.
