vorbisfile

I am trying to write a simple program that uses vorbisfile shared library. But I get a segmentation error when I execute my program. My code is:

Code:

#include <iostream>
using namespace std;

#include <ogg/ogg.h>
#include <vorbis/codec.h>
#include <vorbis/vorbisenc.h>
#include <vorbis/vorbisfile.h>

int main() {
    
    OggVorbis_File * song;
    vorbis_info * songInfo;

    int result = ov_fopen("./song.ogg", song);
    if (result!=0){
    	cout<<"failed";
    	return 1;
    }

    ...
    
    return 0;
}

I am compiling the program with the following line:

g++ -lvorbisfile ogg.cpp

and I receive a Segmentation fault error if the song exists when the application is run. Can you help me with this?

The error is that you pass an uninitialized pointer to an 'OggVorbis_File' object, while the function expects an already existing object of this kind.
The following should get you closer to what you want:

Code:

OggVorbis_File song;

int result = ov_fopen("./song.ogg", &song);
