Answer 1

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:

system("unrar x -ppassword protected_file.rar /destination_directory");

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:

system("unrar x -p1234 file.rar /home/user/");
