Function Documentation

_rol8()

BYTE __stdcall _rol8	(	BYTE	value,
		BYTE	bits
	)

Rotate BYTE left. Defined in _asmop.asm

_rol16()

WORD __stdcall _rol16	(	WORD	value,
		BYTE	bits
	)

Rotate WORD left. Defined in _asmop.asm

_rol32()

DWORD __stdcall _rol32	(	DWORD	value,
		BYTE	bits
	)

Rotate DWORD left. Defined in _asmop.asm

_rol64()

QWORD __stdcall _rol64	(	QWORD	value,
		BYTE	bits
	)

Rotate QWORD left. Note: Max x86 rotation is 31 bits due to register size. Defined in _asmop.asm

_ror8()

BYTE __stdcall _ror8	(	BYTE	value,
		BYTE	bits
	)

Rotate BYTE right. Defined in _asmop.asm

_ror16()

WORD __stdcall _ror16	(	WORD	value,
		BYTE	bits
	)

Rotate WORD right. Defined in _asmop.asm

_ror32()

DWORD __stdcall _ror32	(	DWORD	value,
		BYTE	bits
	)

Rotate DWORD right. Defined in _asmop.asm

_ror64()

QWORD __stdcall _ror64	(	QWORD	value,
		BYTE	bits
	)

Rotate QWORD right. Note: Max x86 rotation is 31 bits due to register size. Defined in _asmop.asm
