1.2.2 Composition of Library
-----------------------------------------

This API is composed of **four C/C++ header files**, platform-specific **library files**, 
and additional **dependency (third-party) library files** required for proper operation
on Linux and Windows environments.

   * - **Dependency Library**
     - **Linux**
     - libPocoFoundation.so  

       libPocoNet.so
     - Poco runtime libraries for Linux

   * - 
     - **Windows**
     - PocoFoundation.dll  

       PocoNet.dll
     - Poco runtime libraries for Windows

.. note::
   - The **Poco** framework is used internally by DRFL for TCP/UDP communication
     and multi-threaded operations.
   - On **Linux**, DRFL and Poco libraries are provided per Ubuntu version.
     Ensure that the correct library path is added or registered using ``ldconfig``.
   - On **Windows**, make sure that the target architecture (**x86** or **x64**)
     matches the provided DRFL library and that required Poco DLLs are accessible
     via the system PATH.
   - Installation of **Microsoft Visual C++ Redistributable** is required on Windows.
