💖 KDK_SYSTEM_LONGFORMAT_TRANSFORM(3) 💖

okay bestie, you found it — the kdk_system_longformat_transform page from the Library Functions Manual (that's section 3, the library-functions girlies). sit down, grab a boba, we're learning date formatting 🍓

✨ NAME ✨

kdk_system_longformat_transform — 长格式转化 (aka: long format transformation, no cap)

🎀 SYNOPSIS 🎀

#include <libkydate.h>

extern char* kdk_system_longformat_transform(struct tm *ptr);

Link with -lkydate.

🦋 Detailed Description 🦋

so the main character function of this interface is: it takes the time you got out of the standard library's struct tm and converts it into a string in the current long format. it's giving glow-up for your timestamps 💅

the argument ptr is a pointer to struct tm.

🌸 RETURN VALUE 🌸

on success, it returns a long formatted date with type of char*. the returned string needs to be released by free — yes, bestie, you have to free it, it's not gonna clean up after itself 🫶

on error, return NULL.

🌈 EXAMPLES 🌈

here's the whole vibe in code, fr fr:

#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;
}
