Stdcall

Back to Reserved words.

The modifier stdcall:

• belongs to the calling conventions for internal and external subroutines;
• pushes the parameters from right to left on the stack;
• aligns all the parameters to a default alignment.

Example:

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

Example 2:

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