 <h4>Description</h4>
 <p>The specified memory address is not that always aligned to word boundary because the argument is defined as <tt>BYTE*</tt>. For more information, refer to the description of <a href="dread.html"><tt>disk_read</tt></a> function.</p>
 <p>Generally, a multiple sector write request (<tt class="arg">count</tt><tt> &gt; 1</tt>) must not be split into single sector transactions to the storage device, or the file write throughput will be drastically decreased.</p>

The write operation to the media does not need to be completed at return from this function by what write operation is in progress or data is only stored into the write-back cache.

The write completion request is done by <tt>CTRL_SYNC</tt> command of <tt><a href="dioctl.html">disk_ioctl</a></tt> function.
