KDK_SYSTEM_GET_BUILDTIME(3)

📦 version 3.0.1.4, in arch rolling, ubuntu resolute, ubuntu stonking

💖 KDK_SYSTEM_GET_BUILDTIME 💖

okay bestie, gather round, because we're doing kdk_system_get_buildTime from the Library Functions Manual, section 3. yes, that one. she's a libkysysinfo girlie and she's here to tell you when your operating system was built. iconic behavior honestly.

✨ NAME ✨

kdk_system_get_buildTime — 获取操作系统构建时间 (aka: get the operating system build time 🕐)

🌸 SYNOPSIS 🌸

#include <libkysysinfo.h>

extern char *kdk_system_get_buildTime()

Link with -lkysysinfo.

bestie do NOT forget the -lkysysinfo linker flag, she will not find you otherwise 💀

🦋 Detailed Description 🦋

The main function of the interface is to obtain operating system build time. that's it. that's the whole job. she shows up, she tells you when your OS got built, she leaves. main character energy fr fr ✨

🎀 RETURN VALUE 🎀

  • On success, returns the operating system build time of type char*; The returned string needs to be released by free.
  • On error, return NULL.
no cap: that string is YOURS to free. free it or you're leaking memory and the vibe check will NOT be passed 😭

🌈 EXAMPLES 🌈

here's the whole little demo program, and yes it's doing a lot more than just build time — it's a whole libkysysinfo tour. we love a versatile queen 👑
