Vorbis dev - Nov 2004 - excecute error II

the code has been modified, the file has opened it as binary (with rb), but it
even
follows the same error.  
the new code is:
/*****************************************/
	OggVorbis_File  musica;
	FILE *archiv =NULL;
	FILE *dec =NULL;

	archiv = fopen("basta.ogg","rb");
	if(archiv==NULL) exit(1);

	int falla = ov_open(archiv,&musica,NULL,0);

	if(falla!=0)
	{
		switch(falla){
			case OV_EREAD :	printf("error de lectura");break;
			case OV_ENOTVORBIS  :	printf("not vorbis file");break;
			case OV_EVERSION  :	printf("version mala");break;
			case OV_EBADHEADER   :	printf("de cabecera");break;
			case OV_EFAULT    :	printf("falla");break;

	}
