# FEX Core SDK — Documentation

Welcome. This is the entry point for the FEX Core SDK 1.4.2 documentation. The SDK gives you a forensic image and filesystem engine accessible through a flat C-style DLL surface. The reference example application (`FexViewer`) is in C#; reference examples in additional languages will land in a future patch.

## API reference (DLL)

Every customer-facing export of `FEX.Core.dll` (and its Linux / macOS counterparts) is documented in one of three places:

- V2 API reference — recommended for all new integrations. The DLL allocates buffers, the caller frees them with `FreeAllocatedBuffer`. This is the default path.
- V3 API reference — column-windowed extraction for huge datasets and partial-column queries. Use this when V2 would materialise more memory than you can spend, or when you only need a small subset of properties.
- Function index — alphabetical "where do I look up X?" reference.

The V1 buffer-pattern surface has been retired from the public docs as of 1.4.2 — the DLL still exports it for binary compatibility but new integrations should use V2 or V3 only.

## Concepts and references

- Types & constants — `TFileRecord`, `TPropertySpec`, `TVersionInfo`, file-status flags, property type enums.
- Memory management — buffer ownership rules and the three patterns. Read once before you write your first integration.
- Error codes — every result code with diagnostic guidance.
- License keys — how to obtain and install your license key.

## Tutorials & best practices

- Common workflows — step-by-step guides for typical forensic tasks.
- Best practices — API selection, performance, coding patterns.

## Platform & deployment

- Windows dependencies — required runtime DLLs.
- Linux dependencies — required `.so` libraries.
- Troubleshooting — common problems and fixes.

## Example code

Language | Path | Notes
--- | --- | ---
C# | `examples/csharp/` (FexViewer) | Canonical reference for 1.4 — IntelliSense XML doc, three subcommands (`info` / `list` / `extract`), pre-built `FexViewer.exe` ready to run.

The DLL surface is the same regardless of binding language — the V2 / V3 API references apply universally, so a Python / C++ / Delphi integration follows the same call shape as the C# example. Reference applications in those languages will be added in a future patch.

## Sample data

`sample-data/sample-image.dd` is a 50 MB FAT32 image included with every SDK distribution. Use it for your first run-through; substitute your own E01 / Ex01 / L01 / DD / DMG / AFF4 once it's working.
