KDK_SYSTEM_LOGIN_LOCK_DATEINFO(3) Library Functions Manual KDK_SYSTEM_LOGIN_LOCK_DATEINFO(3)

kdk_system_login_lock_dateinfo - 获取登录锁屏的时间,星期,长格式日期

#include <libkydate.h>

extern kdk_logn_dateinfo *kdk_system_login_lock_dateinfo(char *user);

Link with -lkydate.

The main function of this interface is to obtain the time, week, and long format date of the logged in user's lock screen.

The argument user is the target username.

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.
