Detailed Description

Utility functions and constants for registers.

Typedef Documentation

◆ ZydisRegisterClass

Defines the ZydisRegisterClass enum.

Please note that this enum does not contain a matching entry for all values of the ZydisRegister enum, but only for those registers where it makes sense to logically group them for decoding/encoding purposes.

These are mainly the registers that can be identified by an id within their corresponding register-class. The IP and FLAGS values are exceptions to this rule.

◆ ZydisRegisterContext

Defines the ZydisRegisterContext struct.

◆ ZydisRegisterWidth

typedef ZyanU16 ZydisRegisterWidth

Defines the ZydisRegisterWidth data-type.

Enumeration Type Documentation

◆ ZydisRegisterClass_

Defines the ZydisRegisterClass enum.

Please note that this enum does not contain a matching entry for all values of the ZydisRegister enum, but only for those registers where it makes sense to logically group them for decoding/encoding purposes.

These are mainly the registers that can be identified by an id within their corresponding register-class. The IP and FLAGS values are exceptions to this rule.
