Title: cardfmt
NAME
====
ft_cardfmt,ft_cardkey,ft_cardset,ft_cardsetl,ft_cardseti,ft_cardsetr,ft_cardsets,ft_cardclr,ft_cardcpy
- Fitsy FITS card set routines.
SYNOPSIS
========
-
FITSCard ft_cardfmt(FITSCard card, char *name, int n, FITSType type, void *value, int prec, char *comm);
FITSCard ft_cardkey(FITSCard card, char *name, int n);
FITSCard ft_cardset(FITSCard card, FITSType type, void *value, int prec, char *comm);
FITSCard ft_cardsetl(FITSCard card, int lvalue, char *comm);
FITSCard ft_cardseti(FITSCard card, int ivalue, char *comm);
FITSCard ft_cardsetr(FITSCard card, double rvalue, int prec, char *comm);
FITSCard ft_cardsets(FITSCard card, char *svalue, char *comm);
FITSCard ft_cardclr(FITSCard card, int ncards);
FITSCard ft_cardcpy(FITSCard card1, FITSCard card2);
-
PARAMETERS
==========
* #"FITSCard card" - FITS card to format.
* #"char *name" - keyword name.
* #"int n" - keyword index number, if is zero no
index number is appended to the
keyword.
* #"FITSType type" - type of the card.
Possible values for a #FITSType are as follows:
* #"FT_COMMENT"
* #"FT_LOGICAL"
* #"FT_INTEGER"
* #"FT_STRING"
* #"FT_VALUE"
* #"FT_REAL"
* #"FT_COMPLEX"
* #"void *value" - pointer to the value to format. The
pointer must be of the apropriate type.
* #"int prec" - If type is FT_REAL the value is formatted
at this precision. Otherwise this parameter
is ignored.
* #"char *comm" - Comment for the card.
* #"int lvalue" - Logical to format as a FITS value.
* #"int ivalue" - Integer to format as a FITS value.
* #"double rvalue" - Double to format as a FITS value.
* #"char *svalue" - String to format as a FITS value.
* #"int ncards" - Number of 80 character FITS cards to clear
* #"FITSCard card1" - Destination card
* #"FITSCard card2" - Source card
DESCRIPTION
===========
ft_cardfmt
----------
Format a FITS card with the supplied values.
ft_cardkey
----------
Format a keyword into a FITS card.
ft_cardset
----------
Format a value into a FITS card.
ft_cardsetl
-----------
Format a logical value into a FITS card.
ft_cardseti
-----------
Format an integer value into a FITS card.
ft_cardsetr
-----------

ft_cardsets
-----------
Format a string value into a FITS card.
ft_cardclr
----------
Clear FITS cards by writing space into them.
ft_cardcpy
----------

EXAMPLES
========
Format the keyword part of a card:
+
FITSHead fits;
FITSBuff card;
FITSCard here;
#ft_cardclr(&card, 1); /* Clear out the card first *-/
#ft_cardkey(&card, "RA"); /* Set the keyword *-/
#ft_cardsetr(&card, 14.789, 3, "OBS RA"); /* Set the value of RA. *-/
here = #ft_cardapp(fits, &card); /* Put the new card into a header*-/
#ft_cardsetr(here, 15.567, 3, FT_Comment); /* Set a new value after it's in
the header and reuse the existing
comment *-/
+
Format the value part of a card:
+
int l = 1;
int i = 15;
double d = 34.7;
char *c = "Shutter";
FITSHead fits;
FITSCard card;
/* Get a card pointer from the header
*-/
card = #ft_cardfind(fits, "Keyword", 0);
#ft_cardsetl(card, l, "A true value");
#ft_cardseti(card, i, "15 is the number");
#ft_cardsetr(card, d, 4, "Four digits of precision here");
/* In this example the special pointer #FT_Comment is used to
use the existing comment in the card.
*-/
#ft_cardsets(card, c, FT_Comment);
