💖 KDK_SYSTEM_GET_NOW_DATEFORMAT(3) 💖

okay so bestie, welcome to the Library Functions Manual section 3, and today's main character is kdk_system_get_now_dateformat — yes that whole name, say it with your chest. 🎀

✨ NAME ✨

kdk_system_get_now_dateformat — 获取当前的日期格式 — aka it gets you the current date format of the system. that's the whole vibe. no cap. 💅

🌸 SYNOPSIS 🌸

#include <libkydate.h>

extern char* kdk_system_get_now_dateformat();

Link with -lkydate.

🫶 friendly reminder: that -lkydate is not optional, she's the whole point. link it or nothing works, fr fr.

🦋 DETAILED DESCRIPTION 🦋

so the main function of this interface — like, her entire purpose, her main character moment — is to obtain the current date format of the system. that's it. that's the job. she's not doing side quests. 👑

💜 RETURN VALUE 💜

  • On success, returns the current date format with type of char*. ✨
💀 IMPORTANT: The returned string needs to be released by free. do NOT forget. she is yours now. you must free her.
  • On error, return NULL.

🔥 EXAMPLES 🔥

okay here's a whole little program, and listen, I'm giving it to you exactly as it is because we do not edit the sacred texts:

#include "libkydate.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <stdlib.h>
#include <glib.h>
#include <glib-object.h>

int main()
{
     int ret = kdk_system_set_long_dateformat("2230年3月4日");
     ret = kdk_system_set_short_dateformat("22/5/3");

     char *ld = kdk_system_get_longformat_date();
     printf("long res = %s0, ld);
     free(ld);

     char *sd = kdk_system_get_shortformat_date();
     printf("short res = %s0, sd);
     free(sd);

     char *ll = kdk_system_get_longformat();
     printf("longformat = %s0, ll);
     free(ll);

     char *ss = kdk_system_get_shortformat();
     printf("shortformat = %s0, ss);
     free(ss);

     struct tm ptr;

     ptr.tm_year = 2322;
     ptr.tm_mon = 9;
     ptr.tm_mday = 3;

     char *lt = kdk_system_longformat_transform(&ptr);
     printf("longformat_transform = %s0, lt);
     free(lt);

     ptr.tm_year = 2022;
     ptr.tm_mon = 3;
     ptr.tm_mday = 2;

     char *st = kdk_system_shortformat_transform(&ptr);
     printf("shortformat_transform = %s0, st);
     free(st);

     kdk_logn_dateinfo *info = kdk_system_login_lock_dateinfo("szm");
     printf("date = %s,time = %s,week = %s0,info->date,info->time,info->week);
     kdk_free_logn_dateinfo(info);

     ptr.tm_hour = 19;
     ptr.tm_min = 3;
     ptr.tm_sec = 2;
     kdk_timeinfo *ti = kdk_system_timeformat_transform(&ptr);
     printf("time = %s, timesec = %s0, ti->time, ti->timesec);
     kdk_free_timeinfo(ti);

    return 0;
}
😭 and yes bestie, the printf format strings in there are exactly like that in the original — %s0 and all. we don't fix, we don't touch, we just vibe. that's the assignment. 🙈
