ZYDIS_EXPORT ZyanStatus ZydisDecoderEnableMode ( ZydisDecoder decoder,
ZydisDecoderMode  mode,
ZyanBool  enabled 
)

Enables or disables the specified decoder-mode.

Parameters
decoderA pointer to the ZydisDecoder instance.
modeThe decoder mode.
enabledZYAN_TRUE to enable, or ZYAN_FALSE to disable the specified decoder-mode.
Returns
A zyan status code.

◆ ZydisDecoderInit()

ZydisMachineMode  machine_mode,
ZydisAddressWidth  address_width 
)

Initializes the given ZydisDecoder instance.

Parameters
decoderA pointer to the ZydisDecoder instance.
machine_modeThe machine mode.
address_widthThe address width.
