Functions allowing retrieval of information about registers.

Function Documentation

◆ ZydisRegisterClassGetWidth()

ZYDIS_EXPORT ZydisRegisterWidth ZydisRegisterClassGetWidth	(	ZydisMachineMode	mode,
		ZydisRegisterClass	register_class
	)

Returns the width of the specified register-class.

Parameters

mode	The active machine mode.
register_class	The register class.

Returns: The width of the specified register.

◆ ZydisRegisterEncode()

ZYDIS_EXPORT ZydisRegister ZydisRegisterEncode	(	ZydisRegisterClass	register_class,
		ZyanU8	id
	)

Returns the register specified by the register_class and id tuple.

Parameters

register_class	The register class.
id	The register id.

Returns: The register specified by the register_class and id tuple or ZYDIS_REGISTER_NONE, if an invalid parameter was passed.

◆ ZydisRegisterGetClass()

ZYDIS_EXPORT ZydisRegisterClass ZydisRegisterGetClass ( ZydisRegister reg )

Returns the register-class of the specified register.

Parameters

reg	The register.

Returns: The register-class of the specified register.

◆ ZydisRegisterGetId()

ZYDIS_EXPORT ZyanI8 ZydisRegisterGetId ( ZydisRegister reg )

Returns the id of the specified register.

Parameters

reg	The register.

Returns: The id of the specified register, or -1 if an invalid parameter was passed.

◆ ZydisRegisterGetLargestEnclosing()

ZYDIS_EXPORT ZydisRegister ZydisRegisterGetLargestEnclosing	(	ZydisMachineMode	mode,
		ZydisRegister	reg
	)

Returns the largest enclosing register of the given register.

Parameters

mode	The active machine mode.
reg	The register.

Returns: The largest enclosing register of the given register, or ZYDIS_REGISTER_NONE if the register is invalid for the active machine-mode or does not have an enclosing-register.

◆ ZydisRegisterGetString()

ZYDIS_EXPORT const char* ZydisRegisterGetString ( ZydisRegister reg )

Returns the specified register string.

Parameters

reg	The register.

Returns: The register string or ZYAN_NULL, if an invalid register was passed.

◆ ZydisRegisterGetStringWrapped()

ZYDIS_EXPORT const ZydisShortString* ZydisRegisterGetStringWrapped ( ZydisRegister reg )

Returns the specified register string as ZydisShortString.

Parameters

reg	The register.

Returns: The register string or ZYAN_NULL, if an invalid register was passed.

The buffer of the returned struct is guaranteed to be zero-terminated in this special case.

◆ ZydisRegisterGetWidth()

ZYDIS_EXPORT ZydisRegisterWidth ZydisRegisterGetWidth	(	ZydisMachineMode	mode,
		ZydisRegister	reg
	)

Returns the width of the specified register.

Parameters

mode	The active machine mode.
reg	The register.

Returns: The width of the specified register, or ZYDIS_REGISTER_NONE if the register is invalid for the active machine-mode.
