如何在c中获取硬盘信息？

#include<windows.h>
#include<stdio.h>

int main() {
    DWORD drives = GetLogicalDrives();
    int i;
    char drive_letter;

    printf("硬盘信息：\n");

    for (i = 0; i < 26; i++) {
        drive_letter = 'A' + i;
        if (drives & 1) {
            printf("%c:\\\n", drive_letter);
        }
        drives >>= 1;
    }

    return 0;
}

#include <sys/statvfs.h>
#include<stdio.h>

int main() {
    struct statvfs stat;

    if (statvfs("/", &stat) == 0) {
        printf("硬盘信息：\n");
        printf("总容量：%lu MB\n", stat.f_blocks * stat.f_frsize / (1024 * 1024));
        printf("可用容量：%lu MB\n", stat.f_bavail * stat.f_frsize / (1024 * 1024));
        printf("已使用容量：%lu MB\n", (stat.f_blocks - stat.f_bfree) * stat.f_frsize / (1024 * 1024));
    } else {
        printf("无法获取硬盘信息\n");
    }

    return 0;
}
