callback

Syntax

callback <name>(<arguments>):

Available in

• File scope

Native C++

Compiled with ordinary DCode function scope; concurrent calls use independent call frames.

Lifecycle

Activation registers the callback. Direct calls and callDcodeCallback wait for a result; supported timeline calls yield only their bucket. startDcodeCallback admits independent background work and returns null, with later failures sent to ARGUS and logs. Calls may overlap. Reactivation replaces the registration; captured calls retain their previous version.

Example

callback name(arguments):
    return null
