   This routine should be used to close open EK files.  EK files 
   open for writing *must* be closed by this routine in order to be 
   valid.  EK files open for read access should also be closed using 
   this routine. 

   1)  Add data to an existing EK file, then close the file. 

          ekopw_c ( "my.ek", &handle );

             [add data] 

          ekcls_c ( handle ); 

   1)  No more than CSPICE_DAS_MAX_OPEN_FILES DAS files may be opened 
       simultaneously. 

       See SpicePar.h for the value of CSPICE_DAS_MAX_OPEN_FILES. 

   1)  If the indicated file is not recognized, no error is 
       signalled. 

   2)  If an I/O error occurs while reading or writing the indicated 
       file, the error will be diagnosed by routines called by this 
       routine. 

   See the EK Required Reading for a discussion of the EK file 
   format.
