- * @brief Rename a device
- *
- * This is a handler for the @c SNDCTL_SETNAME ioctl.
- *
- * See @c http://manuals.opensound.com/developer/SNDCTL_SETNAME.html for
- * more details.
- *
- * From Hannu@4Front:  "This call is used to change the device name
- * reported in /dev/sndstat and ossinfo. So instead of  using some generic
- * 'OSS loopback audio (MIDI) driver' the device may be given a meaningfull
- * name depending on the current context (for example 'OSS virtual wave table
- * synth' or 'VoIP link to London')."
- *
- * @note As the ioctl definition is still under construction, FreeBSD
- * 	 does not currently support SNDCTL_SETNAME.
- *
- * @param wrch	playback channel (optional; may be NULL)
- * @param rdch	recording channel (optional; may be NULL)
- * @param name	new device name gets copied from here
- *
- * @retval EINVAL	Operation not yet supported.
