KDK_SYSTEM_LOGIN_LOCK_DATEINFO(3)                     Library Functions Manual

NAME
       kdk_system_login_lock_dateinfo -
       <?><?><?><?><?><?><?><?><?>,<?><?>,<?><?><?><?><?>

SYNOPSIS
       #include <libkydate.h>

       extern kdk_logn_dateinfo *kdk_system_login_lock_dateinfo(char *user);

       Link with -lkydate.

Detailed Description
       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.

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;     // <?><?>
                   char *time;   // <?><?>
                   char *week;
               }kdk_logn_dateinfo;

       On error, return NULL.
