using dlasrt2 with integer keys

Hi, I've been using dlasrt2 with the API

void dlasrt2 (char *id , MKL_INT *n , double *d , MKL_INT *key , MKL_INT *info );

however i wonder if we can link directly to fortran counterpart to have int keys or if there is a way to feed integer variables to this function as keys, the issue is that right now MKL_INT is a (long long) which takes huge amount of memory for the case i'm running where n=1e10. 

Thanks,
