KDK_SYSTEM_GET_HOSTVIRTTYPE(3)

💖 NAME 💖

kdk_system_get_hostVirtType — the girl whose whole job is finding out what kind of virtual machine the OS host is running on. (original description: 获取操作系统宿主机的虚拟机类型, bestie, it literally says it right there 🫶)

---

✨ SYNOPSIS ✨

#include <libkysysinfo.h>

extern char* kdk_system_get_hostVirtType();

Link with -lkysysinfo.

---

🌸 Detailed Description 🌸

okay so the entire main character energy of this interface is: obtain the virtual machine type of the operating system host. that's it. that's the whole gig. she walks in, checks what you're running inside of, and tells you. no cap. 🎀

---

💅 RETURN VALUE 💅

On success, she hands you back the virtual machine type as a char*. and the content is one of these besties, exactly:

none, qemu, kvm, zvm, vmware, hyper-v, orcale virtualbox, xen, bochs, uml, parallels, bhyve, qnx, arcn, openvz, lxc, lxc-libvirt, systemd-nspawn, docker, podman, rkt, wsl

where none means you're running in a physical environment (raw metal, no vibes, just silicon ✨). every other string represents a specific virtual environment type.

⚠️ the returned string needs to be released by free. do NOT forget. she will not chase you down about it, she trusts you, but like… free her. 🫶

On error, return NULL. 😭
