/*************************************************************************
* Name : PlayTheWave
*
* Description : This function initially opens the wave file to be played
* and tells the MCD information about the file
* that is about to be played. The Samples Per Second,
* Bits Per Sample, and the number of channels with which
* the waveform file was created has to be told to the MCD.
* This function initially fills up the allocated buffer
* of the playlist with the wave file. For 0 - MAXBUFF
* the wave file is filled into the memory. The Wave file
* is read in continously from 0 -MAXBUFF.
* This same buffer is dynamically re-filled again and again
* by the PlayThread thread.
*
* Concepts : The wave file is first opened and then continuously read
* into the buffer. If the end of the wave file is reached
* then we seek to the starting of the wave and keep on reading
* the wave file till the buffer fills up. This displays the
* double buffering concept because, while the playlist is
* continuously looping and playing the wave file, the
* playlist buffers are constantly being filled with data from
* the wave file in the PlayThread thread.
*
*
*
* MMPM/2 API's : mmioOpen
* mmioGetHeader
* mmioRead
* mmioSeek
* mciSendCommand
* MCI_SET
* MCI_CUE
*
* Parameters : None.

* Return : ulReturn
