# API Notes: DiscRecording framework

## Apple documentation

The full API is described in Apple’s documentation, both the C and Objective-C APIs are available (but see the API Notes below).

These bindings are accessed through the `DiscRecording` package (that is, `import DiscRecording`).

## API Notes

This framework exposes both a C API and an Objective-C API. The Objetive-C API is easier to use and should work without problems in Python. The C API is harder to use and requires some manual wrappers to use nicely from Python, those manual wrappers aren’t present at the moment.

## `DRFileProductionInfo`, `DRTrackProductionInfo`

These types are not fully useful at the moment. The types require a manual wrapper that is not yet written.

## `DRSetRefCon`

The ‘refCon’ must be an integer. The ‘callbacks’ argument must be None.

Use `context.register()` if you want to store an arbitrary python object.

Note

Changing the API to allow arbitrary python objects here is not possible as the function `DRGetRefCon` doesn’t return the callback info, and hence PyObjC cannot know how to bridge the result of that function back to python unless we treat is as an arbitrary ‘handle’.
