External

Back to Reserved words.

The external modifier:

• belongs to the calling conventions for external subroutines (eg dynamically loaded libraries);
• allows access to an external subroutine.

Examples:

...
       function funcTest(strTestData : Pchar) : LongWord; cppdecl; external 'Test.dll';
      ...

...
       function funcTest(strTestData : Pchar) : LongWord; cppdecl; external 'test.dylib';
      ...
