Function Documentation

pointer ps2LinuxCreatePrivate (  DeviceIntPtr  pMouse  )

Create a private structure for use within this file.

void ps2LinuxDestroyPrivate (  pointer  priv  )

Destroy a private structure.

void ps2LinuxGetInfo (  DevicePtr  pDev, DMXLocalInitInfoPtr  info )

Fill the info structure with information needed to initialize pDev.

void ps2LinuxInit (  DevicePtr  pDev  )

Initialize pDev.

void ps2LinuxOff (  DevicePtr  pDev  )

Turn pDev off (i.e., stop taking input from pDev).

int ps2LinuxOn (  DevicePtr  pDev  )

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

void ps2LinuxRead (  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.

void ps2LinuxVTPostSwitch (  pointer  p  )

Currently unused hook called after returning from a VT switch.

void ps2LinuxVTPreSwitch (  pointer  p  )

Currently unused hook called prior to an VT switch.
