Vorbis - Apr 2002 - Trying to figure out the library...

I'm new to this list so... Hello everyone :)

Anyway, I want to use Ogg in my Windows-based game but am having trouble
figureing out how to get the library to work.  I downloaded the "Windows
SDK" snapshot and included all the relevant files in my MSVC++ 6.0 project
on Windows 2000, but the examples do not run due to memory overruns.  Here
is some code I tried to run, which is, as far as I can tell from the
documentation, correct.  If anyone can tell me what I'm doing wrong, please
do.

#include <iostream.h>
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <memory.h>
#include "vorbis/codec.h"
#include "vorbis/vorbisfile.h"

int main()
{
        // Open the Ogg file
        FILE * OggFile;
        OggFile = fopen("Yoshi Speak.ogg", "r");
        if (OggFile == NULL)
        {
                cout << "Error Opening file";
                return 0;
        }

        // Make the file into a Vorbis file
        OggVorbis_File vf;
        memset(&vf, 0, sizeof(OggVorbis_File));

<p>        if (ov_open(OggFile, &vf, NULL, 0) < 0)
        {
                cout << "Input does not appear to be an Ogg
bitstream.\n";
                return 0;
        }

<p>        // Clear the Vorbis file (which also closes it)
        ov_clear(&vf);

        // return success
        return 1;
}

The error occurs the moment I call a the ov_open function.  Commenting it
out supresses the error.  The error reads:

Ogg.exe has generated errors and will be closed by WIndowsw  You will need
to restart the program.  An error log is being created. [OK]

If it occurs in debug mode, the error reads:

Unhandled exception in Ogg.exe (NTDLL.DLL): 0x0000005: Access Violation [OK]

And the execution point is shown to be within the assembly code of NTDLL.

Thanks again!

opening the file in binary mode is critical in windows...
so you'll need to change "r" to "rb"...that should solve
the ov_open()
problem...isn't this
in a FAQ somewhere ? *is* there a FAQ somewhere ?
