NAME
       dsinti - initialize the array WSAVE, which is used in subroutine SINT.

SYNOPSIS
       SUBROUTINE DSINTI(N, WSAVE)

       INTEGER N
       DOUBLE PRECISION WSAVE(*)

       SUBROUTINE DSINTI_64(N, WSAVE)

       INTEGER*8 N
       DOUBLE PRECISION WSAVE(*)

   F95 INTERFACE
       SUBROUTINE SINTI(N, WSAVE)

       INTEGER :: N
       REAL(8), DIMENSION(:) :: WSAVE

       SUBROUTINE SINTI_64(N, WSAVE)

       INTEGER(8) :: N
       REAL(8), DIMENSION(:) :: WSAVE

   C INTERFACE
       #include <sunperf.h>

       void dsinti(int n, double *wsave);

       void dsinti_64(long n, double *wsave);

ARGUMENTS
       N (input) Length of the sequence to be transformed.  N >= 0.

       WSAVE (input/output)
		 On  entry,  an array of dimension (2N + N/2 + 15) or greater.
		 SINTI is called once to initialize WSAVE before calling  SINT
		 and  need  not be called again between calls to SINT if N and
		 WSAVE remain unchanged.  Thus, subsequent transforms of  same
		 size  can be obtained faster than the first since they do not
		 require initialization of the workspace.
