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