## ◆ ZYDIS_STATUS_SKIP_TOKEN

#define ZYDIS_STATUS_SKIP_TOKEN ZYAN_MAKE_STATUS(0u, ZYAN_MODULE_ZYDIS, 0x0Bu)

Returning this status code in some specified formatter callbacks will cause the formatter to omit the corresponding token.

Valid callbacks:

- `ZYDIS_FORMATTER_FUNC_PRE_OPERAND`
- `ZYDIS_FORMATTER_FUNC_POST_OPERAND`
- `ZYDIS_FORMATTER_FUNC_FORMAT_OPERAND_REG`
- `ZYDIS_FORMATTER_FUNC_FORMAT_OPERAND_MEM`
- `ZYDIS_FORMATTER_FUNC_FORMAT_OPERAND_PTR`
- `ZYDIS_FORMATTER_FUNC_FORMAT_OPERAND_IMM`
