/* This file tbfxff.c contains the interface between the SPP FITSIO calls
   and the CFITSIO functions.

   Most subroutines begin with fs, but two of them (ftcmsg and ftdrec)
   begin with ft.

   These function names, in upper case and ending in "_U", will be
   converted to similar lower case names by underscore.h.  The
   resulting names will either end in "_" or not, depending on whether
   NO_UNDERSCORE has been defined (see tables$lib/mkpkg.inc).

   Phil Hodge, 22-Mar-1999  File created.
   Phil Hodge,  8-Apr-1999  Change FLEN_KEYWORD to FLEN_VALUE in fsukys.
   Phil Hodge,  7-Sep-1999  Add fsukyj.
   Phil Hodge, 25-May-2000  Add fsgrsz (fits_get_rowsize).
   Phil Hodge, 23-Jun-2000  Add fsukyd.
   Phil Hodge, 12-Sep-2000  Add fsgtbb and fsptbb.
