It is based on the OSS API. It is as follows:<p>Controlling the format data can be done by ioctl commands as follows: SNDCTL_DSP_SETFMT - Set Format of data to and from port AFMT_U8 - Unsigned 8 bit data AFMT_S16_LE - Signed 16 bit data Little Endian SNDCTL_DSP_STEREO - Set number of channels 0 - Mono 1 - Stereo SNDCTL_DSP_SPEED - Sample Rate in samples per second SNDCTL_DSP_SETFRAGMENT - Set buffer sizes 0xMMMMSSSS - 2 to the SSSS power gives size of buffer. MMMM is num of fragments SNDCTL_DSP_GETBLKSIZE - Get fragment size in bytes <p><hr><h2>Constructor & Destructor Documentation</h2><a name="a0" doxytag="aflibDevFile::aflibDevFile"></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"> aflibDevFile::aflibDevFile </td> <td class="md" valign="top">( </td> <td class="mdname1" valign="top" nowrap> </td> <td class="md" valign="top">) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p> </td> </tr></table><a name="a1" doxytag="aflibDevFile::~aflibDevFile"></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"> aflibDevFile::~aflibDevFile </td> <td class="md" valign="top">( </td> <td class="mdname1" valign="top" nowrap> </td> <td class="md" valign="top">) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p> </td> </tr></table><hr><h2>Member Function Documentation</h2><a name="a3" doxytag="aflibDevFile::afcreate"></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"> <a class="el" href="aflib_8h.html#a33">aflibStatus</a> aflibDevFile::afcreate </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">const char * </td> <td class="mdname" nowrap> <em>file</em>, </td> </tr> <tr> <td></td> <td></td> <td class="md" nowrap>const <a class="el" href="classaflibConfig.html">aflibConfig</a> & </td> <td class="mdname" nowrap> <em>config</em></td> </tr> <tr> <td></td> <td class="md">) </td> <td class="md" colspan="2"><code> [virtual]</code></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Main API for opening a file or device in write mode.<p>This function is only used for module support.
