Loads a given native library.
This can be used to resolve dependencies with libraries in various places.
This should work with .dll files on Windows, .dylib files on macOS and .so files on Linux.

Windows error 193 means that 64-bit FileMaker tried to load 32-bit library or 32-bit FileMaker tried to load 64-bit library. The bit level must match between app and library. For macOS the error message will tell you about wrong architecture.

If you like to interface with functions in the DLL, please use CFunction functions.

If you have trouble with DLLs not loading on Windows, please check if you have new Visual Studio Runtime libraries installed. If you need more than one DLL, please use Process.SetDllDirectory to point to the folder to find the DLL files.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.
