<H1><B>Embedded Sound Files.</B></H1>

<P>
By using the open SNDFILE with a file descriptor function:
</P>
<!-- pepper -->
<PRE>
      SNDFILE*  sf_open_fd (int fd, int mode, SF_INFO *sfinfo, int close_desc) ;
</PRE>
<!-- pepper -->
<P>
it is possible to open sound files embedded within larger files.
There are however a couple of caveats:
<P>
<!-- pepper -->
<UL>
	<LI> Read/Write mode (SFM_RDWR) is not supported.
	<LI> Writing of embedded files is only supported at the end of the file.
	<LI> Reading of embedded files is only supported at file offsets greater
			than zero.
	<LI> Not all file formats are supported (currently only WAV, AIFF and AU).
</UL>
<!-- pepper -->
<P>
The test program <B>multi_file_test.c</B> in the <B>tests/</B> directory of the
source code tarball shows how this functionality is used to read and write
embedded files.
