For example, to reset the Bluetooth HCI (and therefore break the connection with the [[Wiimote]]), send a message with the parameters (0x20,0,0,0,0x0300,0) and data 03 0C 00. (0x0300 is the length, 3, in little-endian format). The operation returns the number of bytes read or written.

(0x0300 is the length, 3, in little-endian format). The operation returns the number of bytes read or written. Vectors are an array of the following structure:
typedef struct _ioctlv

void *data;
/** Size of data in byte. */
u32 len;

The same request is used for both sending and receiving data. Which operation is used depends on the endpoint number (>=0x80 are input endpoints, <0x80 are output). The operation returns the number of bytes read or written.

== Example Code: Reset Bluetooth ==
Here is an example code which resets the internal bluetooth dongle and breaks the connection to the wiimote. To compile it, you need devkitPro/devkitPPC and libogc with WII support.
