✨ KDK_SYSTEM_SET_SHORT_DATEFORMAT(3) ✨

okay bestie, welcome to the Library Functions Manual section of the vibe — this is kdk_system_set_short_dateformat from <libkydate.h> and she is, like, the short date format setter. 💅

🌸 NAME 🌸

kdk_system_set_short_dateformat — 设置日期短格式 (yes she's bilingual, we stan a multilingual icon 🫶)

🎀 SYNOPSIS 🎀

#include <libkydate.h>

extern int kdk_system_set_short_dateformat(char *format);

Link with -lkydate. don't forget it, fr fr, the linker will simply not know her otherwise 😭

🦋 Detailed Description 🦋

so the whole main character job of this interface? it sets the short date format. that's it, that's the gig. no cap.

the argument format is the date format itself. and listen — please pass in one of the short formats. the short ones. like, that's the whole point of her, she's the short one, not the long one 🙈

⭐ RETURN VALUE ⭐

  • On success — returns 1 🎉
  • On error — return -1 💀

💖 EXAMPLES 💖

here's the whole little demo, verbatim, no edits, we don't touch the sacred text:

#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;
}

like look at her go, setting the long format and the short format, grabbing dates, transforming struct tms, locking in some login dateinfo for "szm", doing time stuff — a full tour, an absolute serve 🌈

the whole friend group, go say hi:

reminder bestie: pass in a short format, and don't forget -lkydate when you link. that's the whole vibe check. 💅

and that's the page!! this lil cutie came out of the Linux Programmer's Manual, dated Tue Sep 19 2023. mwah, go set some short date formats, you absolute icon 🎀✨🦋
