Safecall

Back to Reserved words.

The safecall modifier:

• belongs to the calling conventions of internal and external subroutines;
• works like the stdcall modifier, with the difference that the register contents are saved and restored.

Example:

function subTest : string; [safecall];
begin
  subTest := 'abc';
end;

Example 2:

...
function funcTest(strTestData : Pchar) : LongWord; safecall; external 'testLibrary.dylib';
...
