How to include a library in Delphi?
--
Previously, I have already included libraries, but after reading the manuals for connecting to Delphi, I realized that it would be better to ask it here.
Usually, libraries are connected with one line of code (JS) or two clicks (C#), but in Delphi they write about some procedures, function exports ...
In my C# library there are classes and methods. There are no procedures.
And the beauty of using a library is that you plug it in and call all its functionality, and not rewrite or adapt it to the application. At least that's how it's done in many languages.
