Yes, call GetObject to load a bitmap data structure and then
GetBitMapBits to get a pointer to the bits. 
EG:
   void WriteBits(hBitmap)
   HBITMAP    hBitmap;
   {
    LONG      lBits;
    BITMAPT   bitmap;
    LPSTR     lpBitmap;
    HANDLE    hBitdata;
     
    GetObject(hBitmap, sizeof(BITMAP), (LPSTR)&bitmap);
    lBits = bitmap.bmHeight * bitmap.bmWidthBytes;
    hBitdata = GlobalAlloc(GM_MOVEABLE, lBits);
    lpBitmap = GlobalLock(hBitdata);
    GetBitMapBits(hBitmap, lBits, lpBitmap);
    _lwrite(file, (LPSTR)&bitmap, sizeof(BITMAP));
    _lwrite(file, lpBitmap, lbits);
    GlobalUnlock(hBitdata);
    GlobalFree(hBitdata);
   }
