Runtime Library

Overview

Diarkis Runtime Library contains the core low-level features of the runtime.

Main Features

  • Core Functions

    • Diarkis TCP/UDP/RUDP communication

    • Thread management

    • Memory management and custom allocator

    • NAT type detection

  • Functionality of each module

Diarkis TCP/UDP/RUDP Communication

The Diarkis Runtime Library supports communication via TCP/UDP/RUDP.

Thread Management

The Diarkis Runtime Library provides Diarkis::DiarkisThread to perform thread operations across multiple platforms. Using Diarkis::DiarkisThread allows you to operate threads with the same interface on all supported platforms.

Memory Management and Custom Allocator

In the Diarkis Runtime Library, users can replace internal memory allocation/deallocation by setting a custom allocator. Implement a custom allocator by inheriting from Diarkis::ICustomAllocator and set it in the runtime using Diarkis::SetCustomAllocator. An implementation sample code can be found in samples/room_broadcast/main.cpp.

NAT Type Detection

The Diarkis Runtime Library provides NAT type detection in collaboration with the Diarkis server.

Functionality of Each Module

For more information on the functionality of each module, we recommend using Diarkis Module. If you want to use the functions of each module directly from the runtime library, please refer to the C++ API Documentation.

Resources Used by the Diarkis Runtime Library

The Diarkis Runtime Library internally allocates and uses the following resources:

  • Sockets

    • Sockets are created per UDP server connection / TCP server connection.

    • UDP:

      • Sockets are created by the runtime library when DiarkisUdp::Connect(Async) or DiarkisUdp::ConnectDualMode(Async) is called.

      • For P2P, sockets created with UDP are used.

    • TCP:

      • Sockets are created by the runtime library when DiarkisTcp::Connect or DiarkisTcp::ConnectDualMode is called.

    • If there are multiple connecting Diarkis servers, you need to create multiple instances of DiarkisInterfaceBase, increasing the number of sockets proportionally to the number of instances.

  • Memory

    • (Coming Soon)

  • Threads

    • One thread is created for TCP connection, and two threads are created for UDP connection.

    • When using the Diarkis client, threads are also created on the Diarkis Module side. For details, refer to Diarkis Threads.

Notes

  • The Diarkis Module API is not thread-safe. If using Diarkis Module in multiple threads, implement exclusive control at the application level.
