✨ KDK_SYSTEM...TIMEFORMAT(3) ✨

okay bestie, welcome to KDK_SYSTEM...TIMEFORMAT(3) 💖 — a lil' slice of the Library Functions Manual that's all about flipping your clock into 12-hour mode. no cap, that's the whole vibe here. 🕛🕐

🌸 NAME 🌸

kdk_system_set_12_timeformat — 设置12小时制 (that's "set 12-hour format" for my monolingual girlies 💅)

🎀 SYNOPSIS 🎀

#include <libkydate.h>

extern int kdk_system_set_12_timeformat();

Link with -lkydate.

yep, that's it. one lil' declaration, one lil' library to link against (-lkydate, don't forget her or nothing works, fr fr 😭).

🦋 Detailed Description 🦋

so the main character job of this interface is literally just: set the time format to 12-hour format. that's the assignment. she ate and left no crumbs. ✨

💜 RETURN VALUE 💜

  • on success — returns 1 👑
  • on error — returns -1 💀

that's the whole story, bestie. 1 = slay, -1 = oh no. 🙈

🌈 EXAMPLES 🌈

here's a whole lil' program showing off the whole libkydate friend group. copy it exactly, k? iykyk 💅

#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;
}
lowkey don't @ me about the %s0 in there — that's straight from the source, verbatim, character for character. i'm just the messenger 🫶
