- * Description:
- * Check various errnos for preadv2(2).
- * 1) preadv2() fails and sets errno to EINVAL if iov_len is invalid.
- * 2) preadv2() fails and sets errno to EINVAL if the vector count iovcnt
- *    is less than zero.
- * 3) preadv2() fails and sets errno to EOPNOTSUPP if flag is invalid.
- * 4) preadv2() fails and sets errno to EFAULT when attempts to read into
- *    a invalid address.
- * 5) preadv2() fails and sets errno to EBADF if file descriptor is invalid.
- * 6) preadv2() fails and sets errno to EBADF if file descriptor is not
- *    open for reading.
- * 7) preadv2() fails and sets errno to EISDIR when fd refers to a directory.
- * 8) preadv2() fails and sets errno to ESPIPE if fd is associated with a pipe.
