# `Control function for bit stream reading`

name
  `TvqGetVectorInfo, TvqWtypeToBtype, TvqUpdateVectorInfo` - TwinVQ control function for bit stream reading
style
  `#include "twinvq.h"
  #include "tvqdec.h"
  void TvqGetVectorInfo(int *bits0[], int *bits1[]);
  int TvqWtypeToBtype(int wtype, int *btype);
  void TvqUpdateVectorInfo(int varBits, int *ndiv, int bits0[], int bits1[]);
  `
function
  These are not called directly from decoder. These are called from TvqReadBsFrame()
  `TvqGetVectorInfo()` gets VQ information at the initialization.
  `TvqWtypeToBtype()` converts windowtype to blocktype. Return 1 if windowtype is invalid, otherwise return 0.
  `TvqUpdateVectorInfo()` updates VQ parameters such as ndiv (number of vectors), and bit0, bit1, depending on varBits.
