NAME
     mlib_VideoDeQuantize_S16   -   dequantization   of   forward
     Discrete Cosine Transform (DCT) coefficients

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_VideoDeQuantize_S16(mlib_s16 icoeffs[64],
          const mlib_d64 dqtable[64]);


DESCRIPTION
     The mlib_VideoDeQuantize_S16() function performs dequantiza-
     tion on DCT coefficients.


     The following equation is used:

       icoeffs[i] = icoeffs[i] * dqtable[i];  0 < i < 64


PARAMETERS
     The function takes the following arguments:

     icoeffs    Pointer to the output DCT coefficients:

                  -2048 < icoeffs[i] < 2048

                Note that icoeffs must be 8-byte aligned.


     dqtable    Pointer to dequantizer table coefficients.


RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:
