[vorbis-dev] access violation in ov_open using VC6

[albert tedja]

source:

#include <vorbis/vorbisfile.h>
#pragma comment( lib, "vorbisfile.lib" )

   FILE* streamFile = 0;
   OggVorbis_File streamOggFile;

<p>   streamFile = fopen( filename, "rw" );
   if ( !streamFile )
   {
      OutputDebugString( "Cannot open the specified
file.\n" );
      exit(0);
   }

   OutputDebugString( "Open file OK.\n" );

   // access violation exception is thrown here.
   result = ov_open( streamFile, &streamOggFile, NULL, 0 );
   if ( result < 0 )
   {
      OutputDebugString( "OggVorbis cannot open the
specified file.\n" );
      fclose( streamFile );
      exit(0);
   }

The exception says:
Unhandled exception in ogg player test.exe (NTDLL.DLL):
0xC0000005. Access Violation.

Disassembly output:
