-
-<P>
- Create or import a FITS header to Fitsy.
-
-<P>
- This is the primary way in which FITSHead structures are created.
-
-<P>
- If <B>cards</B> is not NULL then then <B>acard</B> cards are scanned from the memory
- in search of the END card. When a memory block is passed in to <B>ft_headinit</B>
- then it is considered <I>unmanaged</I> and will not be freed by <B>ft_headfree.</B>
-
-<P>
- If <B>cards</B> is NULL, then <B>acards</B> cards will be allocated for use as a FITSHead.
- If <B>acards</B> is 0 the <B>FT_CARDS</B> will be allocated (36).
-
-<A NAME="section-1.1.4.2"><H4>ft_headcopy</H4></A>
