I want to reproduce the same random numbers that the MS RTL does. To produce the same cardsets Freecell (the windows card game) does when supplying the same game numbers.

The easiest way is to simply call the functions from MSVCRT.DLL.
Almost any computer should have that DLL installed.

I have the DLL, but not the interface.

/* Maximum value that can be returned by the rand function. */

#define RAND_MAX 0x7fff

_CRTIMP int    __cdecl rand(void);
_CRTIMP void   __cdecl srand(unsigned int);



procedure srand(Param1: Cardinal); cdecl;
function rand: Integer; cdecl;
