Translate a C DLL external function declaration to Delphi
Sure, here’s an example of how you can translate a C DLL external function declaration to Delphi:
C DLL function declaration:
__declspec(dllexport) int AddNumbers(int a, int b);
Delphi function declaration:
function AddNumbers(a, b: Integer): Integer; stdcall; external 'MyDll.dll';
In C, the
__declspec(dllexport) keyword is used to specify that a function should be exported from a DLL. In Delphi, the
external keyword is used to specify that a function is implemented in an external library.
int data type in C is equivalent to the
Integer data type in Delphi.
stdcall calling convention in Delphi is equivalent to the
__stdcall calling convention in C. It specifies that the parameters are pushed onto the stack in reverse order, and that the caller cleans up the stack after the call.
MyDll.dll string in the Delphi function declaration specifies the name of the DLL that contains the implementation of the function.

How to add DLL to Delphi?
To add a DLL to a Delphi project, you need to follow these steps:
Go to the “Project” menu and select “Add to Project” -> “DLL…”. This will open a dialog box for selecting the DLL file.
Navigate to the location of the DLL file on your computer and select it.
Delphi will then create an import unit for the DLL, which will allow you to call functions from the DLL within your Delphi project.
To use the functions in your code, add the name of the import unit to your “uses” clause.
Once the import unit is included in your project, you can call the functions in the DLL just like any other function in your code.
Note that you may also need to include any necessary header files or other dependencies for the DLL to work properly in your project.
What is DLL in Delphi?
In Delphi, DLL stands for “Dynamic Link Library.” A DLL is a type of file that contains code, data, and resources that can be used by multiple programs at the same time. The code in a DLL can be loaded and executed by a program at runtime, which allows the program to access the functionality provided by the DLL.
In Delphi, you can create and use DLLs to share code and functionality between different programs or modules. To create a DLL in Delphi, you typically start by creating a new Delphi project and selecting “Dynamic Link Library” as the project type. You can then add code to the project to implement the desired functionality.
Once you have created a DLL in Delphi, you can use it in other programs by importing the functions and procedures defined in the DLL. This is typically done using the “external” directive in Delphi, which allows you to specify the name of the function or procedure in the DLL and the DLL file itself. The program can then call the function or procedure as if it were defined within the program itself.
Overall, DLLs provide a powerful mechanism for code reuse and modular programming in Delphi, allowing you to create complex programs that are easier to maintain and extend over time.
