       COMPLEX X(*), Y(*)
       INTEGER N, INCX, INCY

       SUBROUTINE CSWAP_64(N, X, INCX, Y, INCY)

   F95 INTERFACE
       SUBROUTINE SWAP(N, X, INCX, Y, INCY)

       COMPLEX, DIMENSION(:) :: X, Y
       INTEGER :: N, INCX, INCY

       SUBROUTINE SWAP_64(N, X, INCX, Y, INCY)

       COMPLEX, DIMENSION(:) :: X, Y
       INTEGER(8) :: N, INCX, INCY




   C INTERFACE
       #include <sunperf.h>

       void cswap(int n, complex *x, int incx, complex *y, int incy);

       void cswap_64(long n, complex *x, long incx, complex *y, long incy);



PURPOSE
       cswap Exchange x and y where x and y are n-vectors.


ARGUMENTS
       N (input)
                 On  entry,  N specifies the number of elements in the vector.
                 N must be at least one for the subroutine to have any visible
                 effect.  Unchanged on exit.


       X (input/output)
                 (  1  +  (  n - 1 )*abs( INCX ) ).  On entry, the incremented
                 array X must contain the vector x.  On exit, the y vector.


       INCX (input)
                 On entry, INCX specifies the increment for the elements of X.
                 Unchanged on exit.


       Y (input/output)
                 (  1  +  (  n - 1 )*abs( INCY ) ).  On entry, the incremented
                 array Y must contain the vector y.  On exit, the x vector.


       INCY (input)
                 On entry, INCY specifies the increment for the elements of Y.
                 Unchanged on exit.
