The Solaris audio device in record mode is one. For record mode one must read data in blocks exactly. If the user requests a size different than the audio device block size then we must read the audio device block size and buffer the data and return the requested size from the buffer. This class provides this buffer. <p><hr><h2>Constructor &amp; Destructor Documentation</h2><a name="a0" doxytag="aflibBufferDev::aflibBufferDev"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0">  <tr>    <td class="md">      <table cellpadding="0" cellspacing="0" border="0">        <tr>          <td class="md" nowrap valign="top"> aflibBufferDev::aflibBufferDev </td>          <td class="md" valign="top">(&nbsp;</td>          <td class="mdname1" valign="top" nowrap>&nbsp;          </td>          <td class="md" valign="top">)&nbsp;</td>          <td class="md" nowrap></td>        </tr>      </table>    </td>  </tr></table><table cellspacing=5 cellpadding=0 border=0>  <tr>    <td>      &nbsp;    </td>    <td><p>    </td>  </tr></table><a name="a1" doxytag="aflibBufferDev::~aflibBufferDev"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0">  <tr>    <td class="md">      <table cellpadding="0" cellspacing="0" border="0">        <tr>          <td class="md" nowrap valign="top"> aflibBufferDev::~aflibBufferDev </td>          <td class="md" valign="top">(&nbsp;</td>          <td class="mdname1" valign="top" nowrap>&nbsp;          </td>          <td class="md" valign="top">)&nbsp;</td>          <td class="md" nowrap></td>        </tr>      </table>    </td>  </tr></table><table cellspacing=5 cellpadding=0 border=0>  <tr>    <td>      &nbsp;    </td>    <td><p>    </td>  </tr></table><hr><h2>Member Function Documentation</h2><a name="a4" doxytag="aflibBufferDev::bytes_available"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0">  <tr>    <td class="md">      <table cellpadding="0" cellspacing="0" border="0">        <tr>          <td class="md" nowrap valign="top"> int aflibBufferDev::bytes_available </td>          <td class="md" valign="top">(&nbsp;</td>          <td class="mdname1" valign="top" nowrap>&nbsp;          </td>          <td class="md" valign="top">)&nbsp;</td>          <td class="md" nowrap><code> [inline]</code></td>        </tr>      </table>    </td>  </tr></table><table cellspacing=5 cellpadding=0 border=0>  <tr>    <td>      &nbsp;    </td>    <td><p>Gets the number bytes available to read from the buffer.<p>    </td>  </tr></table><a name="a3" doxytag="aflibBufferDev::getBufferSize"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0">  <tr>    <td class="md">      <table cellpadding="0" cellspacing="0" border="0">        <tr>          <td class="md" nowrap valign="top"> int aflibBufferDev::getBufferSize </td>          <td class="md" valign="top">(&nbsp;</td>          <td class="mdname1" valign="top" nowrap>&nbsp;          </td>          <td class="md" valign="top">)&nbsp;</td>          <td class="md" nowrap> const<code> [inline]</code></td>        </tr>      </table>    </td>  </tr></table><table cellspacing=5 cellpadding=0 border=0>  <tr>    <td>      &nbsp;    </td>    <td><p>Gets the total size of the buffer.<p>    </td>  </tr></table><a name="a2" doxytag="aflibBufferDev::init"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0">  <tr>    <td class="md">      <table cellpadding="0" cellspacing="0" border="0">        <tr>          <td class="md" nowrap valign="top"> bool aflibBufferDev::init </td>          <td class="md" valign="top">(&nbsp;</td>          <td class="md" nowrap valign="top">int&nbsp;</td>          <td class="mdname1" valign="top" nowrap>&nbsp; <em>buf_size</em>          </td>          <td class="md" valign="top">)&nbsp;</td>          <td class="md" nowrap></td>        </tr>      </table>    </td>  </tr></table><table cellspacing=5 cellpadding=0 border=0>  <tr>    <td>      &nbsp;    </td>    <td><p>Initializes the buffer class.<p>This will initialize the buffer class with a size of buf_size.
