# add\_enum

```
add a new enum type
     idx - serial number of the new enum.
           If another enum with the same serial number
           exists, then all enums with serial
           numbers >= the specified idx get their
           serial numbers incremented (in other words,
           the new enum is put in the middle of the list
           of enums).
           If idx >= get_enum_qty() or idx == -1
           then the new enum is created at the end of
           the list of enums.
     name - name of the enum.
     flag - flags for representation of numeric constants
            in the definition of enum.
returns: id of new enum or -1.

long add_enum(long idx, string name, long flag);
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.hex-rays.com/8.4/developer-guide/idc/idc-api-reference/alphabetical-list-of-idc-functions/731.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
