Writing header items

This example (hdrwrite.c) shows how to write a header item to an image.
  /*  Write the header item. */
  hdrOut( "out", " ", "OBSERVER", "The observer.", "Fred Bloggs", 0, istat ); [1]

  /*  Free the image. */
  imgFree( "out", istat );
The following notes refer to the numbered statements:
1.
Note the extra argument which is set to 0. This indicates that a single string ("Fred Bloggs") has been passed. This could also have been set to the value 12, the string length. This argument is of more significance when dealing with multiple images.
