.SH DESCRIPTION
.LP
The 
.I changes->changed 
field indicates which attributes of the device specified in 
.I changes->device 
have changed. The parameters describing the changes are contained in the other 
fields of 
.I changes. XkbGetDeviceInfoChanges 
uses that information to call 
.I XkbGetDeviceInfo 
to obtain the current status of those attributes that have changed. It then 
updates the local description of the device in 
.I device_info 
with the new information.
