#define ZYDIS_FMTFLAG_FORCE_SEGMENTS 0x00000002

Forces the formatter to always print the segment register of memory-operands, instead of ommiting implicit DS/SS segments.

◆ ZYDIS_FMTFLAG_UPPERCASE

#define ZYDIS_FMTFLAG_UPPERCASE 0x00000001

Formats the instruction in uppercase instead of lowercase.

Typedef Documentation

◆ ZydisDecoratorType

◆ ZydisFormatterAddressFormat

typedef uint8_t ZydisFormatterAddressFormat

Defines the ZydisFormatterAddressFormat datatype.

◆ ZydisFormatterDisplacementFormat

typedef uint8_t ZydisFormatterDisplacementFormat

Defines the ZydisFormatterDisplacementFormat datatype.

◆ ZydisFormatterFlags

typedef uint32_t ZydisFormatterFlags

Defines the ZydisFormatFlags datatype.

◆ ZydisFormatterFormatAddressFunc

typedef ZydisStatus(* ZydisFormatterFormatAddressFunc) (const ZydisFormatter *formatter, char **buffer, size_t bufferLen, const ZydisDecodedInstruction *instruction, const ZydisDecodedOperand *operand, uint64_t address, void *userData)

Defines the ZydisFormatterFormatAddressFunc function pointer.

Parameters

formatter	A pointer to the `ZydisFormatter` instance.
buffer	A pointer to the string-buffer.
bufferLen	The length of the string-buffer.
instruction	A pointer to the `ZydisDecodedInstruction` struct.
operand	A pointer to the `ZydisDecodedOperand` struct.
userData	A pointer to user-defined data.

Returns: Returning a status code other than ZYDIS_STATUS_SUCCESS will immediately cause the formatting process to fail.

After appending text to the buffer you MUST increase the buffer-pointer by the size of the number of chars written. Not increasing the buffer-pointer will cause unexpected behavior.

This function type is used for the ZYDIS_FORMATTER_HOOK_PRINT_ADDRESS hook-type.

◆ ZydisFormatterFormatDecoratorFunc

typedef ZydisStatus(* ZydisFormatterFormatDecoratorFunc) (const ZydisFormatter *formatter, char **buffer, size_t bufferLen, const ZydisDecodedInstruction *instruction, const ZydisDecodedOperand *operand, ZydisDecoratorType type, void *userData)

Defines the ZydisFormatterFormatDecoratorFunc function pointer.

Parameters

formatter	A pointer to the `ZydisFormatter` instance.
buffer	A pointer to the string-buffer.
bufferLen	The length of the string-buffer.
instruction	A pointer to the `ZydisDecodedInstruction` struct.
operand	A pointer to the `ZydisDecodedOperand` struct.
type	The decorator type.
userData	A pointer to user-defined data.

Returns: Returning a status code other than ZYDIS_STATUS_SUCCESS will immediately cause the formatting process to fail.

After appending text to the buffer you MUST increase the buffer-pointer by the size of the number of chars written.

Returning ZYDIS_STATUS_SUCCESS without increasing the buffer-pointer is valid and will cause the formatter to omit the current decorator.

This function type is used for the ZYDIS_FORMATTER_HOOK_PRINT_DECORATOR hook-type.

◆ ZydisFormatterFormatFunc

typedef ZydisStatus(* ZydisFormatterFormatFunc) (const ZydisFormatter *formatter, char **buffer, size_t bufferLen, const ZydisDecodedInstruction *instruction, void *userData)

Defines the ZydisFormatterFormatFunc function pointer.

Parameters

formatter	A pointer to the `ZydisFormatter` instance.
buffer	A pointer to the string-buffer.
bufferLen	The length of the string-buffer.
instruction	A pointer to the `ZydisDecodedInstruction` struct.
userData	A pointer to user-defined data.

Returns: Returning a status code other than ZYDIS_STATUS_SUCCESS will immediately cause the formatting process to fail.

After appending text to the buffer you MUST increase the buffer-pointer by the size of the number of chars written. Not increasing the buffer-pointer will cause unexpected behavior.

This function type is used for the ZYDIS_FORMATTER_HOOK_FORMAT_INSTRUCTION, ZYDIS_FORMATTER_HOOK_PRINT_PREFIXES and ZYDIS_FORMATTER_HOOK_PRINT_MNEMONIC hook-types.

◆ ZydisFormatterFormatOperandFunc

typedef ZydisStatus(* ZydisFormatterFormatOperandFunc) (const ZydisFormatter *formatter, char **buffer, size_t bufferLen, const ZydisDecodedInstruction *instruction, const ZydisDecodedOperand *operand, void *userData)

Defines the ZydisFormatterFormatOperandFunc function pointer.

Parameters

formatter	A pointer to the `ZydisFormatter` instance.
buffer	A pointer to the string-buffer.
bufferLen	The length of the string-buffer.
instruction	A pointer to the `ZydisDecodedInstruction` struct.
operand	A pointer to the `ZydisDecodedOperand` struct.
userData	A pointer to user-defined data.

Returns: Returning a status code other than ZYDIS_STATUS_SUCCESS will immediately cause the formatting process to fail.

After appending text to the buffer you MUST increase the buffer-pointer by the size of the number of chars written.

Returning ZYDIS_STATUS_SUCCESS in one of the ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_X hooks without increasing the buffer-pointer is valid and will cause the formatter to omit the current operand.

Returning ZYDIS_STATUS_SUCCESS in ZYDIS_FORMATTER_HOOK_PRINT_OPERANDSIZE, ZYDIS_FORMATTER_HOOK_PRINT_SEGMENT or ZYDIS_FORMATTER_HOOK_PRINT_DECORATOR without increasing the buffer-pointer is valid and signals that the corresponding element should not be printed for the current operand.

Not increasing the buffer-pointer for any other hook-type will cause unexpected behavior.

This function type is used for the ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_REG, ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_MEM, ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_PTR, ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_IMM, ZYDIS_FORMATTER_HOOK_PRINT_OPERANDSIZE, ZYDIS_FORMATTER_HOOK_PRINT_SEGMENT, ZYDIS_FORMATTER_HOOK_PRINT_DECORATOR, ZYDIS_FORMATTER_HOOK_PRINT_DISPLACEMENT and ZYDIS_FORMATTER_HOOK_PRINT_IMMEDIATE hook-types.

ZYDIS_FORMATTER_ADDR_MAX_VALUE	Maximum value of this enum.

◆ ZydisFormatterDisplacementFormats

enum ZydisFormatterDisplacementFormats

Values that represent displacement-formats.

ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_MEM	This function is called to format an memory operand. Replacing this function might indirectly disable some specific calls to the `ZYDIS_FORMATTER_PRINT_ADDRESS` and `ZYDIS_FORMATTER_HOOK_PRINT_DISPLACEMENT` functions.
ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_PTR	This function is called to format an pointer operand.
ZYDIS_FORMATTER_HOOK_FORMAT_OPERAND_IMM	This function is called to format an immediate operand. Replacing this function might indirectly disable some specific calls to the `ZYDIS_FORMATTER_PRINT_ADDRESS` and `ZYDIS_FORMATTER_HOOK_PRINT_IMMEDIATE` functions.
ZYDIS_FORMATTER_HOOK_PRINT_OPERANDSIZE	This function is called right before formatting an memory operand to print the optional size-specifier.
