NAME
     mlibVideoDCT16x16S16S16   -   forward   Discrete   Cosine
     Transform (DCT)

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

     mlibstatus mlibVideoDCT16x16S16S16(mlibs16 coeffs[256],
         const mlibs16 block[256]);


DESCRIPTION
     The input to the DCT routine is the difference  between  the
     current  block and the reference block. The difference pixel
     can occupy nine bits and is represented as a  16-bit  datum.
     The  source  and destination buffer addresses must be 8-byte
     aligned.

PARAMETERS
     The function takes the following arguments:

     coeffs    Pointer  to  the  destination  DCT   coefficients.
               coeffs must be 8-byte aligned.


     block     Pointer to an 16x16 motion-compensated block  that
               is  the difference between the reference block and
               the current block. block must be 8-byte aligned.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
