Return the name of a specified, loaded table. 

   EK 

   Variable  I/O  Description 
   --------  ---  -------------------------------------------------- 
   n          I   Index of table. 
   lenout     I   Maximum table name length.
   table      O   Name of table. 

   n              is the index of the table whose name is desired. 
                  The value of n ranges from 0 to one less than the 
                  number of loaded tables. 

   lenout         is the maximum allowed table name length, including
                  space for the terminating null character.  Normally
                  the caller should allow enough room for 
                  SPICE_EK_TSTRLN characters; this parameter is 
                  declared in the header SpiceEK.h.

   table          is the name of the nth loaded table.  If table
                  is too small to accommodate the name, the name will
                  be truncated on the right.

   None. 

   This routine is a utility that provides the caller with the 
   name of a specified loaded table.  The index of a table with 
   a given name depends on the kernels loaded and possibly on 
   the order in which the files have been loaded. 

   1)  Dump the names of the loaded tables. 

       #include "SpiceUsr.h"
          .
          .
          .
       ekntab_c ( &n );

       for ( i = 0;  i < n;  i++ )
       {
          ektnam_c ( i,      table );
          printf   ( "%s\n", table );
       } 

   None. 

   1) If this routine is called when no files are loaded, the 
      error SPICE(NOLOADEDFILES) is signaled. 

   2) If the input n is out of range, the error SPICE(INVALDINDEX) 
      is signaled. 

   3) If the output string pointer is null, the error SPICE(NULLPOINTER)
      is signaled.

   4) If the output string has length less than two characters, it 
      is too short to contain one character of output data plus a null  
      terminator, so it cannot be passed to the underlying Fortran 
      routine.  In this event, the the error SPICE(STRINGTOOSHORT) is
      signaled.

   5) If the length of table (indicated by lenout) is at least two
      characters but not large enough to contain the output string,
      the output string will be truncated on the right. 

   The returned name is based on the currently loaded EK files.

       Fixed description of exception (5):  replaced "lenout-1"
       with "lenout."  Removed spurious word "clock" from string
       description.
