Detailed Description

A maple device driver.

Anything which is added to this list is capable of handling one or more maple device types. When a device of the given type is connected (includes startup "connection"), the driver is invoked. This same process happens for disconnection, response receipt, and on a periodic interval (for normal updates).

Member Function Documentation

maple_driver::LIST_ENTRY

(

maple_driver

)

Driver list handle. NOT A FUNCTION!

Field Documentation

int(* maple_driver::attach)(struct maple_driver *drv, maple_device_t *dev)

Device attached callback.

This callback will be called when a new device of this driver is connected to the system.

Parameters

drv	This structure for the driver.
dev	The device that was connected.

Returns

0 on success, <0 on error.

void(* maple_driver::detach)(struct maple_driver *drv, maple_device_t *dev)

Device detached callback.

This callback will be called when a device of this driver is disconnected from the system.

Parameters

drv	This structure for the driver.
dev	The device that was detached.

uint32 maple_driver::functions

One or more MAPLE_FUNCs ORed together.

const char* maple_driver::name

The driver name.

void(* maple_driver::periodic)(struct maple_driver *drv)

Periodic polling callback.

This callback will be called to update the status of connected devices periodically.

Parameters

drv	This structure for the driver.
