NAME
       caldate - calendar dates

SYNTAX
       #include	<caldate.h>

       unsigned	int caldate_fmt(s,&cd);
       unsigned	int caldate_scan(s,&cd);

       struct caldate cd;
       char *s;

DESCRIPTION
       A  struct  caldate  value is a calendar date.  It has three components:
       year, month (1...12), and day (1...31).

       caldate_fmt prints cd in	ISO  style  (yyyy-mm-dd)  into	the  character
       buffer  s, without a terminating	NUL.  It returns the number of charac-
       ters printed.  s	may be zero; then caldate_fmt returns  the  number  of
       characters that would have been printed.

       caldate_scan  reads  a calendar date in ISO style from the beginning of
       the character buffer s and puts it into cd.  It returns the  number  of
       characters  read.   If  s  does	not start with an ISO-style date, cal-
       date_scan returns 0.
