ft_cardpar,ft_cardget,ft_cardgetl,ft_cardgeti,ft_cardgetr,ft_cardgets -Fitsy
 FITS card parsing routines.
SYNOPSIS
 
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);
Possible values for a FITSType are as follows:
 These routines parse FITS cards. Usually the header value routines will
 be used instead of these.
ft_cardpar
Parse a FITS card in to its type, value index and comment parts
 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.
ft_cardget
 Return the value of a FITS card in a static buffer.
ft_cardgetl
 Return the value of a FITS card as a logical.
ft_cardgeti
 Return the value of a FITS card as a integer.
ft_cardgetr
 Return the value of a FITS card as a double.
ft_cardgets
Return the value of a FITS card as a allocated string.
 The returned string is allocated with strdup().
RETURNS
ft_cardpar
 The value parameter.
EXAMPLES
                FITSHead        fits;
                FITSCard        card;
                FITSType        type;
                char            value[FT_CARDLEN];
                int             index;
                char            comment[FT_CARDLEN];
                int             im;     /* Is this a primary image? */
        ft_cardpar(card, &type, value, &index, comm);
        card = ft_headfind(fits, "SIMPLE", 0, 0);
        im = ft_cardgetl(card);
