KDK_SYSTEM_LOGN_DATEINFO(3)

NAME
kdk_system_logn_dateinfo - 获取未登录的时间，星期，月份

SYNOPSIS
#include <libkydate.h>

extern kdk_logn_dateinfo *kdk_system_logn_dateinfo(char *user);

Link with -lkydate.

Detailed Description
The main function of this interface is to obtain the time and date of the login interface when no user is logged in.

The argument user is the user name

RETURN VALUE
On success, returns a pointer to a kdk_logn_dateinfo structure is defined in <libkydate.h> as follows:
        typedef struct _kdk_logn_dateinfo{
            char *date; // 日期
            char *time; // 时间
            char *week;
        }kdk_logn_dateinfo;

On error, return NULL.
