+/*
+ * Purpose: Definitions for server applications using the oss_userdev driver.
+ *
+ * This file is part of the oss_userdev driver included in Open Sound
+ * System. However this file is not part of the OSS API. 
+ *
+ * The ioctl calls defined in this file can only be used in dedicated server
+ * applications that provide virtual audio device services to other
+ * applications. For example the userdev driver can be used to create virtual
+ * audio device that connects to the actual soundcard in another system
+ * over internet.
+ *
+ * Applications that use the client devices will use only the OSS ioctl calls
+ * defined in soundcard.h. They cannot use anything from this file.
