- * This header file contains all the declarations required to compile OSS
- * programs. The latest version is always installed together with OSS
- * use of the latest version is strongly recommended.
+ * the following three calls extend the generic file descriptor
+ * interface. AIONWRITE is the dual of FIONREAD, i.e. returns the max
+ * number of bytes for a write operation to be non-blocking.
*
- * {!notice This header file contains many obsolete definitions
- * (for compatibility with older applications that still ned them).
- * Do not use this file as a reference manual of OSS.
- * Please check the OSS Programmer's guide for descriptions

+ * AIOGSIZE/AIOSSIZE are used to change the behaviour of the device,
+ * from a character device (default) to a block device. In block mode,
+ * (not to be confused with blocking mode) the main difference for the
+ * application is that select() will return only when a complete
+ * block can be read/written to the device, whereas in character mode
+ * select will return true when one byte can be exchanged. For audio
+ * devices, character mode makes select almost useless since one byte
+ * will always be ready by the next sample time (which is often only a
+ * handful of microseconds away).
+ * Use a size of 0 or 1 to return to character mode.
