Function Documentation

◆ ZydisRegisterEncode()

ZYDIS_EXPORT ZydisRegister ZydisRegisterEncode ( ZydisRegisterClass  registerClass,
ZydisU8  id 
)

Returns the register specified by the registerClass and the id.

Parameters
registerClassThe register class.
idThe register id.
Returns
The register specified by the registerClass and the id 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
regThe register.
Returns
The register-class of the specified register.

◆ ZydisRegisterGetId()

ZYDIS_EXPORT ZydisI16 ZydisRegisterGetId ( ZydisRegister  reg)

Returns the id of the specified register.

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

◆ ZydisRegisterGetStaticString()

ZYDIS_EXPORT const ZydisStaticString* ZydisRegisterGetStaticString ( ZydisRegister  reg)

Returns the specified register string as ZydisStaticString.

Parameters
regThe register.
Returns
The register string or NULL, if an invalid register was passed.

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

◆ ZydisRegisterGetString()

ZYDIS_EXPORT const char* ZydisRegisterGetString ( ZydisRegister  reg)

Returns the specified register string.

Parameters
regThe register.

Returns the width of the specified register.

Parameters
regThe register.
Returns
The width of the specified register.

◆ ZydisRegisterGetWidth64()

ZYDIS_EXPORT ZydisRegisterWidth ZydisRegisterGetWidth64 ( ZydisRegister  reg)

Returns the width of the specified register in 64-bit mode.

Parameters
regThe register.
Returns
The width of the specified register.
