Macro Definition Documentation

ZYDIS_CHECK

#define ZYDIS_CHECK

(

status

)

Value:

    do \
    { \
        ZydisStatus status_038560234 = status; \
        if (!ZYDIS_SUCCESS(status_038560234)) \
        { \

The zydis status-code to check.

ZYDIS_SUCCESS

#define ZYDIS_SUCCESS

(

status

)

(status == ZYDIS_STATUS_SUCCESS)

Checks if a zydis operation was successfull.

Parameters

status

The zydis status-code to check.

Enumeration Type Documentation

ZydisStatusCodes

enum ZydisStatusCodes

Values that represent a zydis status-codes.

Enumerator
ZYDIS_STATUS_SUCCESS	The operation completed successfully.
ZYDIS_STATUS_INVALID_PARAMETER	An invalid parameter was passed to a function.
ZYDIS_STATUS_INVALID_OPERATION	An attempt was made to perform an invalid operation.
ZYDIS_STATUS_INSUFFICIENT_BUFFER_SIZE	A buffer passed to a function was too small to complete the requested operation.
ZYDIS_STATUS_NO_MORE_DATA	An attempt was made to read data from an input data-source that has no more data available.
ZYDIS_STATUS_DECODING_ERROR	An general error occured while decoding the current instruction. The instruction might be undefined.
ZYDIS_STATUS_INSTRUCTION_TOO_LONG	The instruction exceeded the maximum length of 15 bytes.
ZYDIS_STATUS_BAD_REGISTER	The instruction encoded an invalid register.
ZYDIS_STATUS_ILLEGAL_LOCK	A lock-prefix (F0) was found while decoding an instruction that does not support locking.
ZYDIS_STATUS_ILLEGAL_LEGACY_PFX	A legacy-prefix (F2, F3, 66) was found while decoding a XOP/VEX/EVEX/MVEX instruction.
ZYDIS_STATUS_ILLEGAL_REX	A rex-prefix was found while decoding a XOP/VEX/EVEX/MVEX instruction.
ZYDIS_STATUS_INVALID_MAP	An invalid opcode-map value was found while decoding a XOP/VEX/EVEX/MVEX-prefix.
ZYDIS_STATUS_MALFORMED_EVEX	An error occured while decoding the EVEX-prefix.
ZYDIS_STATUS_MALFORMED_MVEX	An error occured while decoding the MVEX-prefix.
ZYDIS_STATUS_INVALID_MASK	An invalid write-mask was specified for an EVEX/MVEX instruction.
ZYDIS_STATUS_SKIP_OPERAND	Returning this status code in operand-related custom formatter callbacks will cause the formatter to omit the operand.
ZYDIS_STATUS_IMPOSSIBLE_INSTRUCTION
ZYDIS_STATUS_USER	The base value for user-defined status codes.
