OGG Vorbis Decoder Error

I've been trying to create some code in a program I am writing that will decode an OGG Vorbis file. I am using Dev-C++, the newest beta. When I run the compiled program on Windows, I get an error, and the program closes. Here is my code, followed by the flags used in Dev-C++.

Code:

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

#include <gl/glut.h>

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

#include <wx/msgdlg.h>

#ifdef _WIN32
 #include <io.h>
 #include <fcntl.h>
#endif

// Create a buffer for PCM audio output
char pcmout[4096];

// Declare vorbis file global variable
OggVorbis_File OggFile;
int end = 0;
int current_section;

// Create the initialization function
void init()
 {
  glClearColor(1.0,1.0,1.0,0.0);
  glMatrixMode(GL_PROJECTION);
  glLoadIdentity();
  gluOrtho2D(0.0,675.0,500.0,0.0);
 }

// Create the display function
void displayFunc()
 {
  // Clear the screen
  glClear(GL_COLOR_BUFFER_BIT);

  glPushMatrix();

  glColor3f(0.5,0.5,0.5);

  glBegin(GL_LINES);
   glVertex3f(15.0,15.0,0.0);
   glVertex3f(30.0,50.0,0.0);
  glEnd();

  glPopMatrix();

  glutSwapBuffers();
 }

// Create a playback function
void playback()
 {
  if(ov_open(stdin, &OggFile, NULL, 0) < 0)
   {
    wxMessageDialog error(NULL,wxT("Error!"),wxT("The file you specified is not in OGG Vorbis file format, or is corrupt and could not be opened."),wxOK);
    error.ShowModal();
    exit(1);
   }
  
  ov_clear(&OggFile);
 }

// Create the main function
int main(int argc, char *argv[])
 {
  #ifdef _WIN32
   _setmode( _fileno( stdin ), _O_BINARY );
   _setmode( _fileno( stdout ), _O_BINARY );
  #endif

  fopen("YourePitiful.ogg","rb");

  playback();

  glutInitDisplayMode(GLUT_DOUBLE|GLUT_RGB);
  glutInitWindowPosition(50,50);
  glutInitWindowSize(675,500);
  int drawWin = glutCreateWindow("Virtual Turntable Beta 1.0");
  glutDisplayFunc(displayFunc);
  init();
  glutMainLoop();

  fclose(stdin);

  return 0;
 }

Oh, yeah, I forgot to say that I will also be using parts of wxWidgets, mainly alert boxes, and GLUT, too. Even when I try to compile the Vorbis example code, I get the same error.

I've no idea what you're expecting this to do, but you need to assign the return result to a FILE* variable.

It certainly doesn't make it stdin as the rest of your code seems to be.

How do assign it to a FILE* variable. STDIN is a FILE*, so what line of code should I use to set STDIN as "YourePitiful.ogg"?

PS
In case you're wondering, "You're Pitiful" is a Weird Al song.

Oh, wait. I think I found it.

Code:

/* fopen example */
#include <stdio.h>
int main ()
{
  FILE * pFile;
  pFile = fopen ("myfile.txt","w");
  if (pFile!=NULL)
  {
    fputs ("fopen example",pFile);
    fclose (pFile);
  }
  return 0;
}

Thanks! I'll go test this.
