KDK_PACKAGE_GET_VERSION(3)

✨ KDK_PACKAGE_GET_VERSION 💅

okay so bestie, we're in section 3 of the library functions manual today, and this one is kdk_package_get_version — she lives in <libkynetinfo.h> and she's here to tell you what version of a package is on the system. no cap. 🎀

---

🌸 NAME 🌸

kdk_package_get_version — 获取系统中指定包的版本号 (aka: grab the version number of a package you name, straight from the system) 🦋

---

✨ SYNOPSIS ✨

#include <libkynetinfo.h>

extern char* kdk_package_get_version(const char *name);

Link with -lkynetinfo. 🔗

---

💖 DETAILED DESCRIPTION 💖

The main character job of this interface is literally just: get the version number of the package you specify in the system. that's it, that's the whole vibe. 👑

The argument name is the package name. you hand her a name, she hands you a version. periodt.

---

🫶 RETURN VALUE 🫶

On success, she returns the version of type char * — and bestie, listen, the returned string needs to be released by free. like, you have to clean up after her, she's not doing it for you. 🙈

On error, she returns NULL. no version for you, sorry. 💀

🌈 EXAMPLES 🌈

here's the whole thing in action, copy-paste coded and everything:

#include "libkypackages.h"
#include <stdio.h>

static void print_package(kdk_package_t *package)
{
    printf("包名：%s", package->name);
    printf("版本号：%s", package->version);
    printf("包类型：%s", package->section);
    printf("包状态：%s", package->status);
    printf("包大小：%lu0, package->size_kb);
}

int main()
{
    kdk_package_list *list = kdk_package_get_packagelist();
    printf("系统中一共%u个软件包0, list->nums);
    for (size_t i = 0; i < list->nums; i ++)
    {
        print_package(list->list[i]);
    }
    kdk_package_free_packagelist(list);

    printf("Evolution是否安装：%s0, kdk_package_is_installed("evolution", NULL) == 1 ? "是" : "否");
    char *version = kdk_package_get_version("evolution");
    printf("Evolution版本号：%s0, version);
    free(version);

    return 0;
}

see that free(version) at the end? yeah. that's the receipt. don't lose it. 🧾✨
