Procedure

   void pcklof_c ( ConstSpiceChar * filename,
                   SpiceInt       * handle    )

Abstract

   Load a binary PCK file for use by the readers.  Return the
   handle of the loaded file which is used by other PCK routines to
   refer to the file.

Required_Reading

   PCK

Keywords

   FILES


Brief_I/O

   Variable  I/O  Description
   --------  ---  --------------------------------------------------
   filename   I   Name of the file to be loaded.
   handle     O   Loaded file's handle.

Detailed_Input

   filename   Character name of the file to be loaded.

Detailed_Output

   handle     Integer handle assigned to the file upon loading.
              Other PCK routine will subsequently use this number
              to refer to the file.

Parameters

   None.

Exceptions

   1) If an attempt is made to load more files than is specified
      by the paramater ftsize defined in pckbsr_, the error
      SPICE(PCKFILETABLEFULL) is signalled.

   2) The error SPICE(EMPTYSTRING) is signalled if the input
      string does not contain at least one character, since the
      input string cannot be converted to a Fortran-style string
      in this case.

   3) The error SPICE(NULLPOINTER) is signalled if the input string
      pointer is null.

   This routine makes use of DAF file system routines and is subject
   to all of the constraints imposed by the DAF fuile system. See
   the DAF Required Reading or individual DAF routines for details.

Files

   A file specified by filename, to be loaded.  The file is assigned a
   handle by pcklof_c, which will be used by other routines to
   refer to it.

Particulars

   If there is room for a new file in the file table, pcklof_c creates
   an entry for it, and opens the file for reading.

   Also, if the body table is empty, pcklof_c initializes it, this
   being as good a place as any.

Examples

   Load a binary PCK kernel and return the integer handle.

      pck      = "/kernels/gen/pck/earth6.bpc";
      pcklof_c ( pck, &handle );

   Also see the Example in PCKLOF.FOR.

Restrictions

   None.
