# SetDemangledNames

## Description

Setup C++ demangled name representation. IDA can demangle mangled C++ names of the most popular C++ compilers:

* Microsoft
* Borland
* Watcom
* Visual Age
* GNU

The demangled names are represented in two forms: short and long form. The short form is used when a name is used as a reference, the long form is used at the declaration.

You can set how demangled C++ names must be represented:

* as comments: this representation allows you to obtain recompilable source text
* instead of mangled names: this representation makes the output more readable (the disadvantage is that you cannot recompile the output)
* don't display demangled names.

You can setup short and long forms of demangled names. Short form is used when a reference to the name is made; long form is used at the declaration.

To make demangled names more readable, we introduce the possibility to suppress pointer modifiers (near/far/huge).

To demangle GNU C v3.x names, the "Assume GCC v3.x names" checkbox should be set, otherwise such names might not be demangled. Furthermore, to make the demangled name more compact, unsigned types may be displayed as uchar, uint, ushort, ulong. The same with signed basic types.

If the "Override type info" checkbox is set, the demangled name overrides the type information if both are present.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hex-rays.com/ida-9.3/ida-actions/setdemanglednames.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
