That's what my code does do, and then when it needs a buffer to write 
to for playing, this is my code:

unsigned int j;
unsigned int BufferFilled = 0;
unsigned int PlaybackHeaderCount = PlaybackHeaders.size();
char *TempWaveBuffer;

LPWAVEHDR WaveHeader;
MMRESULT mmr;

for(i=0;i<PlaybackHeaderCount;++i)
{
 WaveHeader = PlaybackHeaders[i];
 if(WaveHeader->dwFlags == WHDR_DONE)
 {
  TempWaveBuffer = WaveHeader->lpData;
  ZeroMemory(WaveHeader, sizeof(WAVEHDR));
  WaveHeader->lpData = TempWaveBuffer;
  WaveHeader->dwFlags = 0;
  break;
 }
}

if(WaveHeader->dwFlags != WHDR_DONE)
{
 WaveHeader = new WAVEHDR;
 WaveHeader->lpData = new char[8192];
 WaveHeader->dwFlags = 0;

 PlaybackHeaders.push_back(WaveHeader);
}

And then I use the WaveHeader.
