Expand Up @@ -758,12 +758,14 @@ Each JSON Value has a type and subtype, as specified in the table:
| YYJSON_TYPE_NUM | YYJSON_SUBTYPE_REAL | `double` number |
| YYJSON_TYPE_STR | | String value |
| YYJSON_TYPE_STR | YYJSON_SUBTYPE_NOESC | String value, no-escape |
| YYJSON_TYPE_STR | YYJSON_SUBTYPE_UNIERR | String value, invalid unicode |
| YYJSON_TYPE_ARR | | Array value |
| YYJSON_TYPE_OBJ | | Object value |

- `YYJSON_TYPE_NONE` means invalid value, it does not appear when the JSON is successfully parsed.
- `YYJSON_TYPE_RAW` only appears when the corresponding flag `YYJSON_READ_XXX_AS_RAW` is used.
- `YYJSON_SUBTYPE_NOESC` is used to optimize the writing speed of strings that do not need to be escaped. This subtype is used internally, and the user does not need to handle it.
- `YYJSON_SUBTYPE_UNIERR` marks strings that contained invalid Unicode during parsing. Such strings may require special handling.

The following functions can be used to determine the type of a JSON value.
