FITS card parsing routines.
<A NAME="section-1.1.2"><H3>SYNOPSIS</H3></A>
<PRE>
char *ft_cardpar(FITSCard card, FITSType *type, char *value, int *index, char *comm);
char *ft_cardget(FITSCard card);
int ft_cardgetl(FITSCard card);
int ft_cardgeti(FITSCard card);
double ft_cardgetr(FITSCard card);
char *ft_cardgets(FITSCard card);
<P>
</PRE>
<A NAME="section-1.1.3"><H3>PARAMETERS</H3></A>
<UL>
<P>
<LI> <B>FITSCard card</B> - FITS card to parse.
<LI> <B>FITSType *type</B> - Returned card type.
<P>
Possible values for a <B>FITSType</B> are as follows:
<UL>
<P>
<LI> <B>FT_COMMENT</B>
<LI> <B>FT_LOGICAL</B>
<LI> <B>FT_INTEGER</B>
<LI> <B>FT_STRING</B>

<LI> <B>FT_REAL</B>
<LI> <B>FT_COMPLEX</B>
</UL>
<P>
<LI> <B>char *value</B> - Returned card value string.
<LI> <B>int *index</B> - Returned index of the card keyword.
<LI> <B>char *comm</B> - Returned card comment.
</UL>
<A NAME="section-1.1.4"><H3>DESCRIPTION</H3></A>
<P>
These routines parse FITS cards. Usually the header value routines will
be used instead of these.
<A NAME="section-1.1.4.1"><H4>ft_cardpar</H4></A>
<P>
Parse a FITS card in to its type, value index and comment parts
<P>
The ft_cardpar will parse an 80 character fits card in memory
into its parts according to the standard. Some non-standard
card formats are recognized.
<A NAME="section-1.1.4.2"><H4>ft_cardget</H4></A>
<P>
Return the value of a FITS card in a static buffer.
<A NAME="section-1.1.4.3"><H4>ft_cardgetl</H4></A>
<P>
Return the value of a FITS card as a logical.
<A NAME="section-1.1.4.4"><H4>ft_cardgeti</H4></A>
<P>
Return the value of a FITS card as a integer.
<A NAME="section-1.1.4.5"><H4>ft_cardgetr</H4></A>
<P>
Return the value of a FITS card as a double.
<A NAME="section-1.1.4.6"><H4>ft_cardgets</H4></A>
<P>
Return the value of a FITS card as a allocated string.
<P>
The returned string is allocated with strdup().
