Hi Frank,

That's correct, the fits_read_header() function is not
yet implemented.

To read one or more specific header keywords, one can
use either of these routines:

   struct = fits_read_key_struct (file, X_KEY, ...)
   (x,...) = fits_read_key (file, X_KEY, ...)

For example:

isis> x = fits_read_key_struct ("arf.fits", "DATE", "EXPOSURE");             
isis> print(x);                                                   
    date = 2003-03-02T17:54:00
    exposure = 29079.8
