KDK_DISPLAY_GET_WIDTH(3)

💖 KDK_DISPLAY_GET_WIDTH 💖

okay bestie, gather round, because we're talking about kdk_display_get_width(3) from the Library Functions Manual and honestly? it's giving "small function, big main character energy." ✨

🌸 NAME 🌸

kdk_display_get_width — 获取显卡的数据宽度

like. it gets the data width of your graphics card. that's the whole job. and it does it flawlessly. 💅

---

✨ SYNOPSIS ✨

#include <libkydisplay.h>

extern char* kdk_display_get_width();

and bestie, do NOT forget to link it, or the linker will simply not know her:

-lkyhw

---

🦋 Detailed Description 🦋

so the main function of this interface is to obtain the data width of the Video card. that's it. that's the vibe. she is focused, she is unbothered, she has one (1) job and she ate. 🔥

---

💜 RETURN VALUE 💜

• On success — returns the Video card data width, of type char*. IMPORTANT: that returned string needs to be released by free. like, you have to free her. she is not gonna clean up after herself, bestie, that's on you. 🙈
• On error — return NULL. no drama, just NULL.

---

🎀 EXAMPLES 🎀

here's the full group-chat screenshot of how you'd actually use her (and all her sisters), no cap:

#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 of them gets a lil free() after her? that's the self-care routine. do not skip it. 🧖
