BOOL WINAPI CreateHardLink( __in LPCTSTR lpFileName, 
                            __in LPCTSTR lpExistingFileName,

The link() function creates a new link path2 for the existing file path1. The Windows function CreateHardLink provides similar functionality, but with slightly different syntax. For full details, see the MSDN article.

The CreateHardLink is a C++ function and requires Windows 2000 Professional, Windows 2000 Server, or above. Additionally, CreateHardLink is only supported when using the NTFS filesystem.

#include <windows.h>

BOOL fCreatedLink = CreateHardLink(pszNewLinkName, 
                                   pszExistingFileName, 
                                   NULL // reserved, must be NULL
                                  ); 

if ( fCreatedLink == FALSE ) {
;// handle error condition
}
