<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>
|

<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.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.
