检索 minix 操作系统版本

发布于 2024-08-29 11:42:09 字数 326 浏览 6 评论 0原文

我正在为大学做一个项目，其中（高于其他项目）我必须从 kernell 调用中获取 minix 操作系统版本。这就是我得到的结果（在一些帮助下）：

int main (int argc, char *argv[] )
{
    char M3ca1[23];
    message ml;
    m.m_u.m_m1.m3ca1= OS_VERSION;
    char temp=_syscall(MM,69,&m);
    printf("the os version is %c\n",temp);
    return 0;
}

我收到多个错误。

I'm having a project for the university in which (above others ) i have to get the minix os version from kernell call. This is what i have come to (with some help):

int main (int argc, char *argv[] )
{
    char M3ca1[23];
    message ml;
    m.m_u.m_m1.m3ca1= OS_VERSION;
    char temp=_syscall(MM,69,&m);
    printf("the os version is %c\n",temp);
    return 0;
}

And i get multiple errors.

该代码满足您的要求：

#include <stdio.h>
#include<minix/config.h>

int main(int argc, char**argv) {
    printf("the os version is %s.%s\n",OS_RELEASE,OS_VERSION);
    return 0;
}

如果这是一个大学项目，我怀疑这就是您所要求的。当然，您不会被要求实现一个提供操作系统版本的新系统调用，然后编写一个调用它的小程序？

******** 由于最近的评论，多年后进行编辑 ***

如果您想从运行中而不是静态地获取此信息，您需要查看 uname(2) 联机帮助页。 uname 将为您填充一个结构体，其中包含所有操作系统版本、版本、架构等。

没有正在运行的 minix 机器来组合/验证快速程序来调用和打印此信息。应该是直截了当的。可以用示例程序替换本段。

This code does what you are asking for:

#include <stdio.h>
#include<minix/config.h>

int main(int argc, char**argv) {
    printf("the os version is %s.%s\n",OS_RELEASE,OS_VERSION);
    return 0;
}

If this is a university project I doubt this is what is being asked of you. Sure you aren't being asked to implement a new system call that gives the os version, and then write a small program that calls it?

******** Edit after many years due to a recent comment ***

If you want to grab this from the running current instead of statically, you want to look at the uname(2) manpage. uname will fill a struct for you with all OS release, version, arch, and so forth.

Don't have a running minix machine to put together/verify a quick program to call and print this info. Should be straight forward. Might replace this paragraph with sample program.
