void msLinuxOff ( DevicePtr  pDev  ) 

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

void msLinuxRead ( 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.
