NAME

     ccopy - Copy x to y

SYNOPSIS

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

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

     SUBROUTINE CCOPY_64(N, X, INCX, Y, INCY)

     COMPLEX X(*), Y(*)
     INTEGER*8 N, INCX, INCY

  F95 INTERFACE
     SUBROUTINE COPY([N], X, [INCX], Y, [INCY])

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

     SUBROUTINE COPY_64([N], X, [INCX], Y, [INCY])

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

  C INTERFACE
     #include <sunperf.h>

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

     void ccopy_64(long n, complex *x,  long  incx,  complex  *y,
               long incy);

PURPOSE

     ccopy Copy x to 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 sub-
               routine to have any visible effect.  Unchanged  on
               exit.
     X (input)
               of DIMENSION at least ( 1 + ( n - 1 )*abs( INCX  )
               ).   Before  entry,  the  incremented array X must
               contain the vector x.  Unchanged on exit.

     INCX (input)
               On entry, INCX specifies  the  increment  for  the
               elements  of X.  INCX must not be zero.  Unchanged
               on exit.

     Y (output)
               of DIMENSION at least ( 1 + ( m - 1 )*abs( INCY  )
               ).  On entry, the incremented array Y must contain
               the vector y. On exit, Y  is  overwritten  by  the
               vector x.

     INCY (input)
               On entry, INCY specifies  the  increment  for  the
               elements  of Y.  INCY must not be zero.  Unchanged
               on exit.
