Brief_I/O

   VARIABLE  I/O  DESCRIPTION
   --------  ---  --------------------------------------------------
   sum        I   New summary for current array.

Detailed_Input

   sum         is the new summary for the current array. This
               replaces the existing summary. However, the addresses
               (the final two integer components) of the original
               summary are not changed.

Detailed_Output

   None.

Parameters

   None.

Exceptions

   1)  If this routine is called when no search is in progress in the
       current DAF, the error SPICE(DAFNOSEARCH) is signaled by a
       routine in the call tree of this routine.

   2)  If the DAF containing the "current" array has actually been
       closed, an error is signaled by a routine in the call tree of
       this routine.

   3)  If the DAF containing the "current" array is not open for
       writing, an error is signaled by a routine in the call tree of
       this routine.

   4)  If no array is current in the current DAF, the error
       SPICE(NOCURRENTARRAY) is signaled by a routine in the call
       tree of this routine. There is no current array when a search
       is started by dafbfs_c or dafbbs_c, but no calls to daffna_c or
       daffpa_c have been made yet, or whenever daffna_c or daffpa_c return
       the value SPICEFALSE in the `found' argument.

Files

   This routine operates on a DAF opened for write access. A search
   must be in progress at the time this routine is called; this
   routine replaces the descriptor of the current segment.

Particulars

   See SPICELIB umbrella routine DAFFA.

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) Replace the body ID code 301 (Moon) with a test body ID,
      e.g. -999, in every descriptor of an SPK file.

            Re-pack the descriptor; replace the descriptor
            in the file.

            dafrs_c ( sum );

         }

         /.
         Close the file.
         ./
         dafcls_c ( handle );

         /.
         Find the set of objects in the SPK file.
         ./
         spkobj_c ( fname, &ids );

         printf( "Objects in the DAF file:\n\n" );

      When this program was executed on a Mac/Intel/cc/64-bit
      platform, using the SPK file named de430.bsp, the output was:


      Enter name of the SPK file > de430.bsp
      Objects in the DAF file:

        -999  1  2  3  4  5  6  7  8  9  10  199  299  399

Version

       Edited the header to comply with NAIF standard. Extended
       code example to generate outputs and provided example's solution.

       Fixed typo in -Exceptions entry #3: daffpa_c is used to find the
       previous array, not the non existing API dafbna_.
