caldate(3)		    Library Functions Manual		      caldate(3)

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 characters 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  charac-
     ters  read.   If  s does not start with an ISO-style date, caldate_scan re-
     turns 0.
