Back to Reserved words.


The reserved word library:

  • belongs to shared library programming;
  • identifies a unit as a shared library (DLL);
  • replaces the reserved word unit in shared library units.

Example of the basic structure of a shared library:

library TestLibrary;

{$mode objfpc} {$H+}

uses
  SysUtils;

// library subroutine
function cvtString(strIn : string) : PChar; cdecl;
  begin
    cvtString := PChar(UpperCase(strIn));
  end;

// exported subroutine(s)
exports
  cvtString;
end.
