36 This function fills Length bytes of Buffer with the 64-bit value specified by\r

38 bytes of Buffer.\r

40 If Length > 0 and Buffer is NULL, then ASSERT().\r
41 If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().\r
42 If Buffer is not aligned on a 64-bit boundary, then ASSERT().\r
43 If Length is not aligned on a 64-bit boundary, then ASSERT().\r
