functionOSReadSwapInt16

OS_INLINE uint16_t OSReadSwapInt16(const volatile void * _base, uintptr_t _offset)
▾
claude-fable-5, 2026-08-24 · not from Apple sources · verified against xnu libkern/libkern/arm/OSByteOrder.h
Reads the 16-bit integer at address _base + _offset, tolerating unaligned addresses, and returns it with its bytes reversed. Implements the non-host-order side of the OSReadLittleInt16/OSReadBigInt16 macros.

functionOSReadSwapInt32

OS_INLINE uint32_t OSReadSwapInt32(const volatile void * _base, uintptr_t _offset)
▾
claude-fable-5, 2026-08-24 · not from Apple sources · verified against xnu libkern/libkern/arm/OSByteOrder.h
Reads the 32-bit integer at address _base + _offset, tolerating unaligned addresses, and returns it with its bytes reversed. Implements the non-host-order side of the OSReadLittleInt32/OSReadBigInt32 macros.

functionOSReadSwapInt64

OS_INLINE uint64_t OSReadSwapInt64(const volatile void * _base, uintptr_t _offset)
▾
claude-fable-5, 2026-08-24 · not from Apple sources · verified against xnu libkern/libkern/arm/OSByteOrder.h
Reads the 64-bit integer at address _base + _offset, tolerating unaligned addresses, and returns it with its bytes reversed. Implements the non-host-order side of the OSReadLittleInt64/OSReadBigInt64 macros.

functionOSWriteSwapInt16

▾
claude-fable-5, 2026-08-24 · not from Apple sources · verified against xnu libkern/libkern/arm/OSByteOrder.h
Byte-reverses the 16-bit value _data and stores it at address _base + _offset, tolerating unaligned addresses. Implements the non-host-order side of the OSWriteLittleInt16/OSWriteBigInt16 macros.
