#### Procedure

       cleard_c ( Clear a double precision array )

       void cleard_c ( SpiceInt       ndim,
                       SpiceDouble  * array )

#### Abstract

       Fill a double precision array with zeros.

#### Required_Reading

       None.

#### Keywords

       ARRAY
       ASSIGNMENT

#### Brief_I/O

       VARIABLE  I/O  DESCRIPTION
       --------  ---  --------------------------------------------------
       ndim       I   The number of elements of `array' which are to be
                      set to zero.
       array      O   Double precision array to be filled.

#### Detailed_Input

       ndim        is the number of elements in `array' which are to be
                   set to zero.

#### Detailed_Output

       array       is the double precision array which is to be filled
                   with zeros.

#### Parameters

       None.

#### Exceptions

       Error free.

       1)  If ndim < 1, the array is not modified.

#### Files

       None.

#### Particulars

       None.

#### Examples

       The numerical results shown for this example may differ across
       platforms. The results depend on the SPICE kernels used as
       input, the compiler and supporting libraries, and the machine
       specific arithmetic implementation.

       1) Initialize all members of a double precision array to the
          same value and clear it afterwards.

          Example code begins here.

          /.
             Program cleard_ex1
          ./
          #include <stdio.h>
          #include "SpiceUsr.h"

          int main( )
          {

             /.
             Local parameters.
             ./
             #define NDIM         4

             /.
             Local variables.
             ./
             SpiceDouble          array  [NDIM];

             SpiceInt             i;

             /.
             Initialize all member of the array `array' to 11.5, and
             print out its contents.
             ./
             filld_c ( 11.5, NDIM, array );

             printf( "Contents of `array' before cleard_c:\n" );
             for ( i = 0; i < 4; i++ )
             {
                printf( "%6.1f", array[i] );
             }
             printf( "\n" );

             /.
             Clear the contents of `array' and print it.
             ./
             cleard_c ( NDIM, array );

             printf( "\n" );
             printf( "Contents of `array' after cleard_c:\n" );
             for ( i = 0; i < 4; i++ )
             {
                printf( "%6.1f", array[i] );
             }
             printf( "\n" );

             return ( 0 );
          }

          When this program was executed on a Mac/Intel/cc/64-bit
          platform, the output was:

          Contents of `array' before cleard_c:
            11.5  11.5  11.5  11.5

          Contents of `array' after cleard_c:
             0.0   0.0   0.0   0.0
