CALDATE(3)

NAME
caldate - calendar dates

SYNOPSIS

#include <caldate.h>
unsigned int \fBcaldate_fmt\fP(\fIs\fR,&\fIcd\fR);
unsigned int \fBcaldate_scan\fP(\fIs\fR,&\fIcd\fR);
struct caldate \fIcd\fR;
char *\fIs\fR;

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 characters read. If s does not start with an ISO-style date, caldate_scan returns 0.
