| 85 * Note about bitfields: The UINT8 type is used for bitfields in ACPI tables. 86 * This is the only type that is even remotely portable. Anything else is not 87 * portable, so do not use any other bitfield types. | 85 * Note: C bitfields are not used for this reason: 86 * 87 * "Bitfields are great and easy to read, but unfortunately the C language 88 * does not specify the layout of bitfields in memory, which means they are 89 * essentially useless for dealing with packed data in on-disk formats or 90 * binary wire protocols." (Or ACPI tables and buffers.) "If you ask me, 91 * this decision was a design error in C. Ritchie could have picked an order 92 * and stuck with it."
