用c打开rar文件
我必须用 C 编写代码才能在 Windows 中提取受密码保护的 rar 文件。我不知道如何做到这一点。有人能给我建议或提供一段示例代码吗？我将非常感激。
编辑：
这是我用来打开 rar 文件的代码。在系统命令 ranjit 中是密码。它给出了模块+文件名中未定义的符号系统错误。有人可以帮助我吗？两天以来我一直在努力解决这个问题。 编辑：此代码打开存档但不提取它。如果我在命令行中使用 unrar 命令，它会提取文件。我该怎么办？
#include<stdio.h>
#include<stdlib.h>
int main(int argc, char **argv)
{
char file[20];
char file2[50] = "F:\\Program Files\\WinRAR\\unrar.exe";
printf("enter the name of the rar file : ");
gets(file);
puts(file);
system(("%s e -p ranjit %s >C:\stdout.log 2>C:\stderr.log",file2, file));
getchar();
return 0;
}
I have to write code in C to extract a password protected rar file in windows. I don't have any clue about how to do this. can anybody suggest me something or provide a sample piece of code? I will be very thankful.
EDIT:
This is the code I am using to open the rar file.In the system command ranjit is the password. It's giving the error undefined symbol_system in module+thefile name. Can anybody help me?? I am struggling on this since two days.
EDIT: This code opens the archive but do not extract it. If I uses the unrar command in command line, it extracts the file. What I should I do?
#include<stdio.h>
#include<stdlib.h>
int main(int argc, char **argv)
{
char file[20];
char file2[50] = "F:\\Program Files\\WinRAR\\unrar.exe";
printf("enter the name of the rar file : ");
gets(file);
puts(file);
system(("%s e -p ranjit %s >C:\stdout.log 2>C:\stderr.log",file2, file));
getchar();
return 0;
}

除了 karlphilip 的建议之外，http://www.rarlabs 上还有一些可能很有趣的资源。 com/rar_add.htm。
我特别认为 UnRAR.dll 和 UnRAR 源 可能相关。不过我现在还不能真正检查一下。
In addition to what karlphilip's suggestions there's also a couple of potentialliy interesting looking resources at http://www.rarlabs.com/rar_add.htm.
In particular I am thinking UnRAR.dll and UnRAR source may be relevant. I can't really check it out at the momment though.
使用 unrar 库 - 将文件提取到文件流缓冲区
但如果您正在寻找纯 C 解决方案，请查看： http://www.unrarlib.org/
引用他们的常见问题解答：URARFileLib（UniquE RAR 文件库的简称，也称为 unrarlib）是 C 程序员访问 RAR 存档的免费库。
另一种方法system() 调用命令行工具（例如unrar ）已经安装在您的系统上来完成这项工作：
例如，假设受保护的文件名为file.rar，密码为1234并且目标目录是/home/user，您可以使用以下参数调用system()：
Using unrar library - extracting files into a filestream buffer
But if you're looking for a pure C solution, take a look at: http://www.unrarlib.org/
Quote from their FAQ: The URARFileLib (short name for UniquE RAR File Library, also called unrarlib) is a free library for C programmers to access RAR archives.
Another approach, which I just tested successfully, doesn't require the use of external libraries to decompress rar files. Use system() to invoke a command-line tool (such as unrar ) already installed on your system to do the job:
For instance, let's say the protected file was named file.rar, the password was 1234 and the destination directory was /home/user, you would call system() with the following parameters:
