# Core Functions



## Important Payload Limit
Keep payloads under 20,480 bytes. This is the maximum size the engine can send or receive at one time. If you expect a response larger than 20,480 bytes, provide a callback function so the mod can use its internal fetch/chunking flow and deliver the reconstructed data to your callback.

This section contains documentation for the core functions of ArmaDragonflyClient that handle initialization, process management, and scheduling.

## Available Functions

- [addTask](addTask.md) - Add a task to the scheduler
- [handler](handler.md) - Handle callbacks from the extension
- [init](init.md) - Initialize the database system
- [printAddonName](printAddonName.md) - Print the addon name
- [processQueue](processQueue.md) - Process queued database operations
- [scheduler](scheduler.md) - Schedule database operations
- [test](test.md) - Test the database connection

## Example Usage

```sqf
// Initialize the database
[] call dragonfly_db_fnc_init;
