| 20 By using the open SNDFILE with a file descriptor function: | |
| 21 </P> | |
| 22 <!-- pepper --> | |
| 23 <PRE> | |
| 24 SNDFILE* sf_open_fd (int fd, int mode, SF_INFO *sfinfo, int close_desc) ; | |
| 25 </PRE> | |
| 26 <!-- pepper --> | |
| 27 <P> | |
| 28 it is possible to open sound files embedded within larger files. | |
| 29 There are however a couple of caveats: | |
| 30 <P> | |
| 31 <!-- pepper --> | |
| 32 <UL> | |
| 33 <LI> Read/Write mode (SFM_RDWR) is not supported. | |
| 34 <LI> Writing of embedded files is only supported at the end of the file. | |
| 35 <LI> Reading of embedded files is only supported at file offsets greater | |
| 36 than zero. | |
| 37 <LI> Not all file formats are supported (currently only WAV, AIFF and AU). | |
| 38 </UL> | |
| 39 <!-- pepper --> | |
| 40 <P> | |
| 41 The test program <B>multi_file_test.c</B> in the <B>tests/</B> directory of the | |
| 42 source code tarball shows how this functionality is used to read and write | |
| 43 embedded files. | |
