KDK_FREE_DATEINFO(3)

💖 KDK_FREE_DATEINFO 💖

okay bestie, welcome to the Library Functions Manual 🎀 this page is the one for kdk_free_dateinfo, and ngl it's a short one — but it's important, because it's literally the cleanup crew for the libkydate date-info family. no cap. 🧚

---

✨ NAME ✨

kdk_free_dateinfo — 释放由 kdk_system_tran_dateformat 返回的日期信息结构体

for my besties who don't read Chinese: this is the one that frees the date information structure that kdk_system_tran_dateformat gave you. she's the cleanup girlie. 🫶

---

🌸 SYNOPSIS 🌸

#include <libkydate.h>

extern void kdk_free_dateinfo(kdk_dateinfo *date);

and you link it with -lkydate, periodt. 🔥

---

🦋 Detailed Description 🦋

The main function of this interface is to release the date information structure returned by kdk_system_tran_dateformat. 💅

The argument date is a pointer of type structure kdk_dateinfo.

like… that's it. that's the whole job. she takes the pointer, she lets the struct go. iconic, honestly. ✨

---

🌈 RETURN VALUE 🌈

No return value.

she gives you nothing back and she doesn't need to. she's giving void and she's thriving. 💀

💜 EXAMPLES 💜

here's the whole demo, copied exactly because we do not mess with the code:

#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;
}

notice how many different free-ers there are in there?? free(), kdk_free_logn_dateinfo(), kdk_free_timeinfo()… and our girl kdk_free_dateinfo() is right there in the same family. a whole squad of deallocators. 🍓

fr fr though — every one of those names is exactly as written in the original, typos and all. I am not touching a single character. 🙈

👑 CONFORMING TO 👑

These functions are as per the withdrawn POSIX.1e draft specification. 👀 yes, withdrawn — she's vintage, she's archival, she's a draft spec that never made it to the big leagues, and we respect her anyway. 💅

The following functions are Linux extensions:

kdk_system_get_dateformat(), kdk_system_set_dateformat(), kdk_system_set_24_timeformat(), kdk_system_set_12_timeformat(), kdk_system_get_now_dateformat(), kdk_system_get_now_timeformat(), kdk_system_tran_dateformat(), kdk_system_nowtime(), kdk_system_nowdate(), kdk_system_shortweek(), kdk_system_longweek(), kdk_system_second(), kdk_system_logn_dateinfo(), kdk_system_gjx_time(), kdk_date_freeall(), kdk_free_logn_dateinfo(), kdk_system_set_long_dateformat(), kdk_system_set_short_dateformat(), kdk_system_get_longformat_date(), kdk_system_get_shortformat_date(), kdk_system_get_longformat(), kdk_system_get_shortformat(), kdk_system_longformat_transform(), kdk_system_shortformat_transform(), kdk_system_login_lock_dateinfo(), kdk_system_timeformat_transform() and kdk_free_timeinfo().

that's the whole roster. the whole friend group. 🦋
