    About Procedur…

    Procedures and functions, referred to collectively as routines, are self-contained statement blocks that can be called from different locations in a program. A function is a routine that returns a value when it executes. A procedure is a routine that does not return a value. Function calls, because they return a value, can be used as expressions in...

    Calling Conventions

    When you declare a procedure or function, you can specify a calling convention using one of the directives register, pascal, cdecl, stdcall, safecall, and winapi. For example, Calling conventions determine the order in which parameters are passed to the routine. They also affect the removal of parameters from the stack, the use of registers for pas...

    In Delphi, functions are self-contained blocks of code that return a value when executed. They are used to perform specific tasks and can be called from different locations within a program.

    Example

    function AddNumbers(a, b: Integer): Integer;
    begin
    Result := a + b;
    end;

    procedure TForm1.Button1Click(Sender: TObject);
    var
    sum: Integer;
    begin
    sum := AddNumbers(5, 10);
    ShowMessage('Sum is: ' + IntToStr(sum));
    end;
    コピーしました。

    In this example, the AddNumbers function takes two integer parameters and returns their sum. The Button1Click procedure calls this function and displays the result.

    Important Considerations

    Declaring Functions

    When declaring a function, you specify its name, parameters, and return type. The function body contains the code that executes when the function is called.

    Calling Conventions

    Delphi supports various calling conventions like register, pascal, cdecl, stdcall, and safecall. These conventions determine how parameters are passed to the function and how the stack is cleaned up.
