[Vorbis-dev] Regarding static codebooks.

HI,
All help is appreciated.
I am trying to print out the static codebooks after they have been
unpacked. For this I wrote a small function as below and put it in
codebook.c
This function does print out the codewords, but somehow is failing to
print the codevalues (prints only zeros and -1). Probably I am making
some mistake while calling _book_unquantize function.
Can someone please verify if the below is correct?

#ifdef _SK_DEBUG
void printStaticCodebook(static_codebook *s){
ogg_uint32_t *codelist;
float *valuelist;
int i, j;
codelist=_ogg_malloc(s->entries*sizeof(*codelist));
codelist=_make_words(s->lengthlist,s->entries,0);
valuelist= _book_unquantize(s,s->entries,NULL);
fprintf(stderr, "Entry#, CodeWordLen, Codeword (Hex), CodeValues
(Hex)\n");
for(i=0;i<s->entries;i++){
if (s->lengthlist[i]){
fprintf(stderr, "%4d, %4d,%8x, ", i, s->lengthlist[i], codelist[i]);
if(s->maptype==1 || s->maptype==2){
for(j=0; j<s->dim; j++){
fprintf(stderr, "%f, ", valuelist[i*s->dim+j]);
}
}
fprintf(stderr, "\n");
}
}
}
