ask_ida/c++ is a specialized AI coding assistant designed to simplify development workflows for IDA Pro and Hex-Rays decompiler users working in C++. Built as part of the open-source ask_ida ecosystem, it addresses the complexity of navigating the IDA SDK, decompiling binary code, and developing plugins by providing direct, actionable C++ code examples tailored to IDA's unique architecture. By focusing on IDA-specific operations like IDB database management, netnode storage, and Hex-Rays decompilation, it eliminates the need for manual SDK documentation research, enabling developers to focus on solving reverse engineering and binary analysis challenges.
Core features of ask_ida/c++ include real-time integration with IDA Pro's SDK functions, support for modern plugin structures (e.g., plugmod_t), and streamlined handling of critical components like effective addresses (ea_t), memory management with qalloc/qfree, and logging via msg(). These features ensure that users can quickly retrieve function names, manipulate IDB data, and decompile code without wrestling with low-level SDK intricacies, making it an indispensable tool for anyone working with IDA's powerful binary analysis capabilities.
Ideal for reverse engineers, malware analysts, plugin developers, and security researchers, ask_ida/c++ accelerates workflows by providing pre-tested code snippets for common tasks such as function name retrieval, netnode operations, and plugin initialization. Whether debugging a binary, automating analysis, or building custom tools, users gain immediate access to IDA's full potential, reducing development time and minimizing errors associated with manual SDK integration.
qstring func_name; get_func_name(&func_name, get_screen_ea()); This directly fetches the function name by combining the current screen address () with IDA's SDK function.To initialize ask_ida/c++: Include necessary headers (e.g., 'ida.hpp'), link against IDA Pro SDK libraries. Open the target binary with idaapi::open_file(), initialize the decompiler context, and use idaapi::get_func() to retrieve decompiled function details.
The SDK includes IDA Pro core APIs (binary loading, disassembly), decompilation utilities (idc for code analysis), plugin frameworks (idaapi::plugin_t), and tools for error handling, memory management, and callback registration to extend IDA functionality.
Handle warnings by setting verbosity with idaapi::get_decompiler_options(), register error callbacks via idaapi::set_error_callback(), and check return codes of decompilation functions (e.g., idaapi::decompile()). Inspect intermediate data structures for incomplete code details.
Yes, use IDA scripting (idc) with loops to open files, decompile, extract functions/signatures, and export results. Leverage idaapi::process_batch() for sequential processing or multi-threaded workflows if supported by the SDK.
Pitfalls include SDK version mismatches, uninitialized IDA APIs, and thread-safety issues. Always initialize IDA with idaapi::init(), validate plugin registration, and test with small binaries to avoid crashes or incorrect decompilation.

They need quick access to IDA's SDK to retrieve function names, analyze decompiled code, and manipulate IDB data. ask_ida/c++ simplifies these tasks by providing pre-built code snippets for function name retrieval, netnode operations, and decompilation, enabling faster analysis of complex malware or obfuscated binaries.
Developers building tools or plugins that interact with IDA (e.g., IDAPython extensions, custom analysis scripts) require deep IDA SDK knowledge. ask_ida/c++ reduces the learning curve by offering modern plugin examples, memory management guidance, and IDB database operations, allowing them to integrate IDA into larger workflows (e.g., automated code review pipelines) without extensive SDK research.
Plugin developers aim to extend IDA's capabilities with custom tools (e.g., auto-renaming, code injection detection). They need to adhere to IDA's modern plugin structure (plugmod_t), handle netnodes, and manage memory safely. ask_ida/c++ provides up-to-date code patterns, ensuring plugins are compatible with future IDA versions and avoid deprecated APIs, streamlining development and reducing maintenance overhead.
Security researchers focus on identifying vulnerabilities in software or malware by analyzing code flow and binary structure. ask_ida/c++ helps them quickly decompile critical code paths, map function calls, and store analysis notes (via netnodes), enabling faster identification of injection points, buffer overflows, or logic flaws in target binaries.
Educators and students learning binary analysis, low-level programming, or decompilation benefit from ask_ida/c++'s practical examples and SDK guidance. It provides hands-on code snippets for real-world IDA workflows, making abstract concepts (e.g., netnodes, IDB databases) tangible and accelerating mastery of reverse engineering fundamentals.
