KDK_DISPLAY_GET_DESCRIPTION(3)

💖 KDK_DISPLAY_GET_DESCRIPTION 💖

okay bestie, welcome to the libkydisplay corner of the manual, aka Library Functions Manual territory. we're gonna talk about kdk_display_get_description and it's lowkey the moment.

---

✨ NAME ✨

kdk_display_get_description — 获取显卡的说明 🌸

(yes the description of the description is in Chinese, we contain multitudes, we are bilingual icons 💅)

---

🎀 SYNOPSIS 🎀

#include <libkydisplay.h>

extern char* kdk_display_get_description();

and listen: you gotta link it, or it's giving nothing. Link with -lkyhw 🫶

---

🦋 DETAILED DESCRIPTION 🦋

so the whole point of this function, the main character energy of the interface, is literally just to obtain the Video card description. that's it. that's the job. it walks up, it reads the description, it hands it to you. iconic behavior honestly. ✨

---

🌈 RETURN VALUE 🌈

• On success — it returns the Video card description, and the type is char*. and bestie, the returned string needs to be released by free. not optional. not vibes-based. free it or you're leaking, and we don't do that here. 💀
• On error — it returns NULL. no cap.

🚨 real talk: every string this family of functions hands you is yours to free. the manual says it, i say it, the group chat says it. periodt.

💜 EXAMPLES 💜

here's the whole glow-up in one file, all the sibling functions invited to the party 🎉

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

int main()
{
    char *vendor = kdk_display_get_vendor();
    printf("生产厂商：%s\n", vendor);
    free(vendor);
    char *product = kdk_display_get_product();
    printf("型号：%s\n", product);
    free(product);
    char *description = kdk_display_get_description();
    printf("设备类型：%s\n", description);
    free(description);
    char *id = kdk_display_get_physical_id();
    printf("物理id：%s\n", id);
    free(id);
    char *bus = kdk_display_get_bus_info();
    printf("总线地址：%s\n", bus);
    free(bus);
    char *version = kdk_display_get_version();
    printf("设备版本：%s\n", version);
    free(version);
    char *width = kdk_display_get_width();
    printf("数据宽度：%s\n", width);
    free(width);
    char *clock = kdk_display_get_clock();
    printf("频率：%s\n", clock);
    free(clock);
    char *capabilities = kdk_display_get_capabilities();
    printf("功能：%s\n", capabilities);
    free(capabilities);
    char *configuration = kdk_display_get_configuration();
    printf("配置：%s\n", configuration);
    free(configuration);
    char *resources = kdk_display_get_resources();
    printf("资源：%s\n", resources);
    free(resources);
    return 0;
}

notice the pattern? get it, print it, free it. get it, print it, free it. that's the whole choreography, and honestly? slay. 💅

⭐ CONFORMING TO ⭐

okay so these functions are as per the withdrawn POSIX.1e draft specification. yes, withdrawn. it's giving "we still reference it anyway" and we respect that. 🙈

and the following functions are Linux extensions: kdk_display_get_vendor(), kdk_display_get_product(), kdk_display_get_physical_id(), kdk_display_get_bus_info(), kdk_display_get_version(), kdk_display_get_width(), kdk_display_get_clock(), kdk_display_get_capabilities(), kdk_display_get_configuration() and kdk_display_get_resources().

(not kdk_display_get_description() itself, just so we're clear — that one's the POSIX.1e-draft one. iykyk 👑)
