Function Documentation

void kbdUSBCtrl (  DevicePtr  pDev, KeybdCtrl *  ctrl )

Set the LEDs.

void kbdUSBGetInfo (  DevicePtr  pDev, DMXLocalInitInfoPtr  info )

Fill the info structure with information needed to initialize pDev.

void kbdUSBInit (  DevicePtr  pDev  )

Initialize pDev using usbInit.

int kbdUSBOn (  DevicePtr  pDev  )

Turn pDev on (i.e., take input from pDev).

void kbdUSBRead (  DevicePtr  pDev, MOTIONPROC  motion, ENQUEUEPROC  enqueue, CHECKPROC  checkspecial, BLOCK  block )

Read an event from the pDev device. If the event is a motion event, enqueue it with the motion function. Otherwise, check for special keys with the checkspecial function and enqueue the event with the enqueue function. The block type is passed to the functions so that they may block SIGIO handling as appropriate to the caller of this function.
