KDK_DISPLAY_GET_RESOURCES(3)

💖 KDK_DISPLAY_GET_RESOURCES(3) 💖

okay bestie, so this one lives in the Library Functions Manual, and it's literally the glow-up page for kdk_display_get_resources(). grab a strawberry 🍓 and let's go.

✨ NAME ✨

kdk_display_get_resources — 获取显卡的资源

(yes the description is in Chinese, no I will not be translating away the vibes, it means "get the resources of the graphics card" and it ate 💅)

---

🎀 SYNOPSIS 🎀

#include <libkydisplay.h>

extern char* kdk_display_get_resources();

and then, the part everyone forgets and then cries about at 2am: Link with -lkyhw. 🔗 do not skip this. do not pass go. do not collect your linker errors.

---

🌸 Detailed Description 🌸

so the whole main character job of this interface is to obtain the resources of the Video card. that's it. that's the assignment. it walks up to the GPU and is like "hey queen, what you working with" and the GPU answers. 👑

---

💜 RETURN VALUE 💜

• On success — you get back the Video card resources, and the type is char*. 🎉 but bestie listen: the returned string needs to be released by free. the string is yours now. you are its guardian. free it or leak it forever, those are the options.
• On error — you get NULL. that's it. that's the whole message. 💀

not me being dramatic but genuinely, free the string. every single time. the free is not optional and it is not a suggestion.

🌈 EXAMPLES 🌈

okay so here's the full little demo, every getter living its best life, each one freed like a responsible icon:

#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;
}

see how every single one gets its free? that's the energy. be like that. 🫶
